my car turns over but wont start

i have power at both of the relays and there is 4 things that go into the relay. I have power on one of the 4. I have no check enginge light when it is on on. and i do not have any power on the octane booster. should i still check the igniton switch? or not?

did you check under hood fuses
i did included the pic before
and did you replace the relay?
if not yet turn key on and tap on the relay look for check engine if it comes on start and if it start replace the relay for sure
i think if all fuses ok you should start with new relay
good luck

i did not replace the relays yet but me and my friend pushed around the relays and the check engine light turned on and we tryed to get the relays to click again and we did get them by moving the relays around and we started the car and took it for a drive. My friend than took off the duck tape and we couldnt start it after that. ill change the relays and than if that does not work i will check the wires cause it seems to be a loose wire.

good
very good
lets check the wiring too>>
any way the relay should be replaced

do you have a wiring diagram for a 1993 ford escort lx 1.9L 4 cylinder this way i can go to the relays and find the wires that connect to the engine so i can check what is loose.

what was the outcome of checking voltage at blue wire at the ignition switch?

did not check that

your right at the finish line, you just have to cross it, we cant deviate from proper diagnostics or we will just waste time. if we find that there is no power at the blue wire then we know we need to check power feed to ignition switch or we simply have a bad ignition switch causing the problem. so we have to follow order or we will be running around in circles.

i tryed to take off the thing under the steering wheel and it wouldnt come off. what do i need to take off the thing right under the steering wheel that is black or the thing thats near the floor? and can you please find me a picture of what you are talking about?

unfortunately service manuals dont show you pictures like the ones you are looking for, they tell you to remove lower steering column panels and after that its up to you to get it off. if i was sitting in your drivers seat and looking under your dash i could tell you exaqctly how to remove each screw but we are limited to what we can do from across the country. just be patient its all nuts and bolts, just keep taking out screws until it comes off.

I don’t understand why you re doing all this to your self
did you try a new relay
I thing you should
its cheep enough and I think you should start with a new relay
when you taped on that relay the car started
if you still need the wiring diagram let me know

ya please send me the wiring diagram

i got the steering colum off but i just do not know what wire it is? ill send you a picture of what i got off and the wires just to tell my which wire i need to test.

if there is a fat blue wire in there check that for 12v when the key is in run position. im at work right now and is hard to get to computer, check all the wires at the switch(good picture) tell me what color wire has power all the time and which wires have power when the key is on. ill be back soon.

bmr what feed that 15a ignition fuse, he said no power ther with key on, all i found was a blue wire from ignition switch feeding the fuse power but i dont see a blue wire in his picture from the ignition switch

do you know where the wires of the 2 relays go? and do you know where the ground is for those 2 relays?

i still think that the relays should be changed

At the PCM relay we have
WHT-DK GRN ------------------> hot at all time
WHT -RED ------------------------> ground PCM
BLK-WHT ---------------------------> hot with key on or and start
BLK-GRN -------------------------> GROUND

check these wires bmr has illustrated. what are you missing? tell me. tell me. tell me.

can the relays be causing this problem?

what is the pcm relay? i dont know how to find the transaxle

thanks for all the help guys i found the problem it was the ignition switch. didnt even change the relays went to ford and they sayed change the ignition switch and i did and it started


thanks

seve12345 you were right there 5 days ago. if you had only checked the ignition switch output on that blue wire, you would have been driving a lot sooner. anyway good job.

Hey I hope the guys who helped this fella are still around. I have a 94 escor with a 1.9 liter and have a crank but no start condition. I have check all the things you instructed th o.p. to check and have voltage on the blue ignition wire and my relays click and have continuity but still no spark at the coils, brand new coil by the way. I'm leaning towards the computer as the issue, how do I continue from here, please help?

Hello,

Can you hear the pump come on in the fuel tank for five seconds when the key is turned on without cranking the engine? Here is a guide to help you get started:

Please run down this guide and report back.

Yes the fuel pump works just no spark.

I've done all the guides said to do, I definitely do not have spark. I have a new crank sensor but have not put it in yet. The relay is absolutely good, I pulled it out and tested continuity through it and there is a click when installed. My check engine light comes on when key is turned as well. Have to go to work now I will check in later, thanks for the help.

I would do the crankshaft sensor first. here is a video that shows a similar car getting the sensor replaced:

Please let us know what you find. We are interested to see what it is.

I've already pulled the crank sensor and ohms it out and compared it to the new one and they are the same. but I will install the new one anyway and report back.

Yep, a sensor can still be bad even though it tests good. Let me know.

Changed it, but found the real problem. Internally broken spark wire, looked new but tested bad. Found the car has blown head gasket also though. so I will be doing a head,water pump,and timing belt. Thank you for the help.
