Crank no start

Code 700 just means there is another fault code in the Transmission Computer. Simple code readers only read fault codes in Engine Computers. The 700 code is used to inform of the need to use a scanner to read the codes in the other computers.

Once you have the codes read in the Transmission Computer, I have a suspicion it will refer to the transmission range switch. That takes the place of the older neutral safety switch. That sensor needs to tell the Engine Computer the transmission is in "park" so it can turn on the starter relay.

Nice start to the new year.

Glad to know you have it under your belt now.

Have a great day.

Thanks, same to you.

Hi. Within the last 6 months, the Cruiser has irregularly had trouble starting. When the ignition is engaged, it will just "click". It initially appeared to be a bad battery. So, I replaced the battery. Within days after the new battery purchase, the vehicle failed to start. I took it to a mechanic who tested the starter, battery, and alternator. He found that the battery was again drained but everything else he reported was fine. He suggested I take the battery back for replacement. I took the battery back to Autozone and had it replaced with an upgrade. The Cruiser started fine for a couple of weeks. However, it happened once again and I had it towed to Pepboys who diagnosed the problem as a bad starter. The starter was replaced and the car ran fine for about a month and a half before it happened again, this time while I was out of town. I had a third mechanic who tested the electrical system for two days to locate the potential battery drain, but he found nothing wrong. Since that time, the Cruiser has failed to turnover on two other occasions. Each time a jump start corrected the problem. Any ideas on what else can be looked into to resolve this issue would be greatly appreciated.

Thanks in advance,
JC

Hi:
It sounds like a problem with the alt. Have they checked it's output when the battery is good and let me know what you find. Out of curiousity, has the engine ever dies while driving?

Joe

Hi Joe,

Yes, the first and third mechanics tested the alternator output and didn't find any problems either time. I have someone check it again, though. Couldn't hurt.

On the other note, the engine never dies or stalls while driving.

I am wondering if it is possible that there might be a short somewhere in the system. But I don't kinow how to test item or even how to talk to a mechanic about it. Any suggestions?

Thanks,
JC

hi:
Yes it could be a short. Try something. Check the battery voltage with the battery connected and disconnected. Let me know what you find.

I have a 2003 Cruiser Trubo, one day it just died at an intersection, mechanics have said the fuel pump is working just fine. Spark plugs, battery, timing belt, everything is fine, it just wont start. My moter said she used to have anissue with a sensor, but couldn't go beyond that, are you aware of any common sensor/computer error that prevent the fuel from flowing?

I know nothing about cars, but I just can't afford to keep having her towed to different mechanics.

Do below to determine if its a fuel or spark problem something has to give

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard i

We are having problems with the car not cranking!
WE have changed the battery, the starter, belts,
sent it back to the shop and it cranked the morning that
They were going to come pick it up so we drove it there instead...they kept it for almost 2 weeks and it cranked every time. Today on Monday , August 24,2009 It will not start! Has ANY ONE ELSE HAD THIS PROBLEM ?? PLEASE HELP US FIND OUT WHAT IS GOING ON...
OUR NEIGHBOR HAS THE SOME PROBLEM WITH HIS CHEVY TRUCK AND HE SAID IT WAS THE ANTI THIEF SYSTEM ON HIS TRUCK AND IT HAS A MIND OF ITS OWN.
IT will go a few times to crank then it won't then go out side and try and try atleast 5 to 10 times then it will crank...
So this car doesn't have an anti - thief system.
Please help!!

If it was me I'll check and test the ignition switch. When you turn key to run you should hear the fuel pump come on and have power to the coil/s check this

Thank you for your answer...
but this car doesn't make that kind of sound.
it just makes a click..we do not hear the fuel pump.
so Now what?

No cranking at all/nothing could mean ignition switch, park and neutral switch, starter relay and starter.

Can't hear the fuel pump check the fuel pump fuse and relay for a start

had the auto shop to come pick it up..they are the ones that changed the starter.. when they arrived they checked it and said once again it is the starter. that sometimes
there are starters that are bad? guess I will see....thank you for your reply I will keep you posted.

I have a 2003 pt cruiser gt turbo have put a lot of money in it ran great for awhile.Now when I shut it off and go back out to start it it turns over real fast but wont start.Turn key off then on again turns over fast for about 15 seconds then starts.Has been doing this all day long I use car for work and need help thanks.

IF it is turning over really fast, it makes me think you have valves sticking open so it loses compression. Check engine compression when it doesn't start to see if it is low.

The motor has been flush and new oil,heads redone,new water pump,new timing belt,new plugs,new wires,new fan and motor,all new gaskets.So what else does it need I mean you shut it down and it does start but then some times it will just crank over and not start.But then it will start 5or 6 times in a row then turn over 15 seconds then start. I am a former marine and have work on cars for a long time but this is wierd out of work and no extra money.

When you said it cranked really fast, I thought maybe there was low or no compression. When it doesn't start, have you checked to see if there is spark and fuel to the engine?

I took 2003 pt cruiser gt turbo to shop for code error only 1 and says #1loose or missing drive belt not that,#2 alternator defective not that,#3battery defective not that,#4 poor electrical connection check that and everything is tight.Dont know what it is it will crank over fine and start then other times I crank it over it takes 10 to 15 seconds then starts Im to the point of shooting it and getting it out of misery. Thanks Marine29

The car won't start dash says no fuses I replaced all of the ignition fuses both in car and behind the battery under the hood any ideas?

If its cranking over and will not start go to this link: https://www.2carpros.com/articles/car-cranks-but-wont-start and Won't crank over at all/nothing: https://www.2carpros.com/articles/car-engine-will-not-crank-over

My car lost water and overheated on the way to work. Once I knew the car was overheating I drove it about 1 mile to the nearest gas station. I was able to add water and get the car started and drove it about 3 blocks to the work parking lot. Afternoon I put stop lead in the radiator to try to get the car back home. The water leak or hose leak stopped. I decided to try to take it home rather than leaving it in the parking lot thinking the only problem was a leaking hose and I could repair it. However on the way home the car would not run faster than 45 miles per hour and if a strain or pull was placed on the engine the car would die and I would have to wait about 15 minutes before the car would restart. I checked the oil and the level was low origianally, about 1 quart but I added oil and the level was good. Do I have a severe engine problem?

When it is running, is there white smoke coming from the exhaust?

NO. There is no white smoke coming from the engine. Could it just be a tune up problem?

I doubt the tune up is the problem if it was running well before. If you lost power after the overheat, my guess is there is a bad head gasket or a warped head.

I have a 2003 pt cruiser i have replaced head gasket, waterpump, radiator, thermostat and all upper engine gaskets also installed a new battery. The car ran before but over heated numerous times. After reassembly the car will not start. I have no spark but i am getting fuel pressure. Engine codes p0107 map/baro circuit low input, p0122 throttle/pedal position sensor switch a circuit low input. These codes come back soon as they are erased. Then when i crank the engine code p0340 cam position sensor A circuit bank 1 or single sensor circuit malfunction...it is a single sensor. And p0335 crankshaft position position sensor circuit malfunction. It has a 2.4L non-turbo automatic transmission. Please help.

All of these codes can be set if the common 5 volts is missing to the sensors. Measure all three wires at the throttle position sensor. In this case you can unplug it and measure right on the terminals. Expect to find 5.0 volts on the center terminal, but you need to find it on one of the end terminals. If it's missing suspect that wire is cut or grounded. If it is grounded, the Engine Computer will shut the 5.0 volt supply down to protect it. Once the short is removed you usually have to cycle the ignition switch off and back on to reset it.

I found the problem. I had tested all aspects of the circuits they had ground and 4.8 volts reference..which is common due to internal resistance in the copper wire. I pulled all connectors off all sensors and found the cam sensor connector and coil pack connector were the same design. I switched the two around and all codes went away and car runs great and no longer overheats. Thanks for you time and efforts to direct resolution to my question.... Mectec2012.

I don't think I would have figured that one out. Very happy to hear it's solved.

You just said everything a mechanic needs to know or at least this one anyway, but I only have 30 years experience and I can honestly say that I have not seen everything and I am still learning new stuff everyday. back to your problem. you said wife cranked car but timing belt was not turning but it feels tight?? well your timing belt hasn't broke so its tight, but I guarantee you there is several teeth gone on the belt problem around the crank where most of the engine torque comes from. So it has no teeth to turn belt, cams etc., but isn't broken so belt feels tight. I just hope you check those valves!

This post is over a year old so I am not sure this will help them but it will surely help others.

Thanks again. Please let us know if there is anything you need help with in the future. Thanks
