1988 Chevy Celebrity WON'T START

are you getting gas to the injectors?

https://www.2carpros.com/articles/car-cranks-but-wont-start

if not check for voltage at fuel pump with key on and cranking, if nothing check the relay, if its good and no gas is coming out pump is bad.

next to check the injectors throw a noid light to the wiring connectors and crank the engine, it should flash, if not you have no injector pulse. let me know what you find.

The fuel pump is running when you first turn on the ignition, and I am pretty sure that I am getting gas to the injector as when the old injector was in the car, the plastic was broken-the reason for replacement, I jumpered the ground side and it sprayed fuel. Is a noid light just a 12v light that you connect to the injector connector? I suspect that I might not be getting any pulses. Is the pulses sent from the same module that fires the spark plugs, and can it be replaced seperately from the coils to the spark plug?

i dont know if your model has a crank shaft sensor on the account of the age of the vehicle.

the injectors should have constant 12v with the key on. when the engine is cranking or running the computer groudns out the harness causing the pulse to happen.

it collects this information from the crank and cam position sensor, MAF sensor, coolant temp sensor, iat sensor, and o2 sensors.

a noid light is a solenoid light

not a regular 12v light, use a noid light.

where can I get this noid light, from a autoparts store or is this a dealer item. I have never heard of a noid light, but I am old school, carb, dist, and spark plugs.

a noid light can be bought or rented at any autopart store just about.

be sure you have a volt meter also.

I got the noid light and hooked it up. I did not get any flashes when I cranked the engine.

I got the noid light and hooked it up. No flashes when the engine is being cranked.

next check for power with the key on, should be constant positive.

there should be no ground untill the engine is cranked, should flash not stay lit.

if you have the + with key on but no ground suspect a bad crank or cam position sensor or ecm.

Check the fuel pressure if its within specs and injection pulses

MY 1988 CLEBRITY TURNS OVER BUT WONT START.
IT DOES NOT HAVE ANY SPARK AND IVE ALREADY CANGED THE IGNITION MODULE. IT STILL HAS NO SPARK WHAT ELSE COULD I DO TO FIND A SOULUTION TO MY PROBLEM. THANK YOU.

Take a test ligkt to coil check for power then place light on the other trem. crank Does light blink? if so coil

hey my aunts 1988 chevy celebrity 4 cyl died on me the other day when i stopped at a red light, i went to start it but it didnt start. so i then added gas to its carborator and it started up n i reved it up and then dropped it in to 2nd, and drove it in to the parking lot. then it died. went to start it again and it didnt start, so i added gas to the carborator and it started up when i put my foot on the gas pedal. then when i went to put it in to drive it stalled n wouldnt start, it wont start with out having gas put in the carborator. what could be the issue? i had the fuel pump fuel filter and fuel injector replaced all at the same time about 3 or 4 months ago. i just need help to figure this out. thanks

Hello, when you first turn the key on, no crank, can you hear the pump run for a couple of seconds? Check fuel pressure, use a gage.

There is a prime connector, underhood, driverside, firewall, between the master cylinder and fender. Shows to be gray wire with electrical connector, nothing plugged into it. It should be in plain site. Use a jumper wire, run voltage to the connector, the pump should run, you don't have to use the key. Use an inline fuse on the jumper, just in case. right now, I'm all for checking out the fuel pump/circuits.

engine cranks but no fire. does get gas but no spark at plugs need help

Welcome fordman, engine cranking, is there injector spray pattern? If no spray pattern and no spark, I'd look for rpm signal comes from crank sensor goes to ignition module, from module to pcm. I'd also check B+ and ground at the ignition module. Any codes?

I'm at a loss, trying to clean up a mess left by another mechanic. I've got good fuel pressure, injector pulse, new ign module & tune up. I also swapped the ECM from another running 2.8 Celebrity. The car still has no spark. What am I missing?

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

I have changed coil packs and spark plug wires along with plugs but I must have crossed plug wires since the car will not start. Can you tell me from the coil packs which wire goes to each plug

First you have to tell us what engine you have.

2.8 six cylinder

I was just given the car and it does not start. It gets spark, and cranks, but I don't think it's getting fuel. It had the pump replaced around 30,000 miles ago, but that was like 4 yrs ago. A mechanic said that it needs to be replaced again. Is there any other likely fixes, I'd like to start simple before I make it complicated. Any ideas?

a fuel pump is not complicated. it is a straight forward job. there is a fuse behind the right front headlight for it and if it is blown, then the pump is seized.

Roy

So if it's a 20 amp fuse, it's not blown. But I can't hear the fuel pump when I turn the key to the on position either. Any other ideas?

Where is the fuel pump relay located so I can start simple and work from there?

right where the fuse was located. there is a single primer wire that when you apply 12 volts it goes right to the pump and bypasses all controls.

Roy

check for proper fuel supply first then look at filter and sock of the fuel pump. common on older vehicles.

scan for codes and check fuel pressure first. fp should be 41-47 psoi

Will not start.

So I checked the fuse, and if it's a 20 amp fuse its intact.

When the ignition is in the "on" position, I can't hear the fuel pump. I would like to try to keep the repair cost as low as possible for now so I would like to replace the fuel pump relay first. Anyone able to tell me where that is? Also if anyone has any other idea as to what might be causing it not to start, I am all ears...

try smacking fuel tank with palm of hand hard. sometimes they start, dont'know for how long but it works sometimes. if you have a 2.5L it's on the right side of firewall rear of engine. 2.8Lpic attached.
