    They did not have the security key in 88 on the camaro!! This car has been sitting up and the boy wants to try and get it going again!!

    i never said it was in the key itself. it might be in the ignition module itself. its a much older type of security feature that was used on a lot of older gms, mine included

    when you start the car do you hear the fuel pump and if you do does it stay running. On these cars the oil pressure sender controls the fuel pump.The relay controls fuel pump priming after the motor starts the oil pressure sender sends power to the pump. If you have no oil pressure or the sender is bad the pump will shut off cutting the fuel to the injectors making them appear to stop.

    on some gm cars there was a security feature where if the spare or valet key was used more than three time the car wouldnt start up for more 5 seconds at a time. also, have you been in any sort of accident with it or checked your fuel pressure yet?

  • mikehumble May 11, 2010

    if your key has a chip in it try another key. this problem may be a security issue but i do not remember if they used this system in 88

Getting no power to fuel pump fuse no power to ignition fuse


no engine stated.!

fuses good,? 12vdc on both sides key on?

spark good on all cylinders.??????????

this is first. not fuel, fuel is dead last.

if above is ok the engine runs on test fuel.

if the engine runs for say 3 seconds on test fuel, and SOUNDS

great, that means the spark and engine are ok, leaving>?

FUELING only.

easy , right?

if true all that, then the scan tool is next.

wont buy one,? like most here? (you cant fix cars with no scan tool)



make up or buy a NOID lamp. (a small 12vdc lamp)

see if the injectors are all firing.

if not, the PCM is cutting fuel.

if the injectors fire (electric pulse) then it may be fuel relay not closing.

did you check for 12vdc (11vdc min) at the pump? cranking

you must crank it and check,

there are 3 kinds of cars. (we assume last)

1: pump runs keyon, full time, (illegal now)

2: pump runs for 3 seconds, and stops keyon, (for priming only)

3: runs only cranked, (most cars) and runs running engine.



see that logic there?

some cars cut pump and injection with no spark. ( to cut fires)

this logic is inside the PCM brain, called firmware.

just assume the car is smarter and use #3 above. on all cars

and I win..



the scan tool will show errors cranked for 5 seconds.

does it?



now why i cant leave generic help and answer specifcially

no engine stated.

to fix them you need to know whats there, first.



the line up

1.4 L E-TEC I4 (petrol)

1.6 L E-TEC I4 (petrol)

1.8 L Family II I4 (petrol)

2.0 L Family II I4 (petrol)

2.0 L RA 420 I4 (diesel)





next time post the engine in your car.

open hood , look up see EPA sticker there and engine type?

USA answers... all. of mine, as this is a USA forum../

try to add to one post for one problem not make many unique posts. stay on NO START. please.

Cerokee 3,1td startoff solenoid


which engine, no engine stated means answers will be wrong.
so??????????????????
that above is a statement so will run with that.
so what makes you think there is no fuel pressure??
1: the pressure gage is way low? how low , that you connected.
2: the pump seems silent. (near useless test)
3: pump never gets 12vdc cranking, you must crank.
4: the dribble test fails. (wasted time) (rail drips)
5: the injectors seem all dry, (spark plug tips are all dry)

now EFI 101 (crash course)
THE EFI system will be dead if fuse are blown.
and the ECU never injects with spark errors.
or CKP errors
or CMP errors
or IMMO is active. immobilizer is unhappy see lamp, look at it.

if all that works good, the ASD closes
the injectors fire
and the car starts if the ECU/PCM sees any errors stated above
it drops out in 2seconds <KILLING all injections,.
this is the PCM logic hard coded for fire prevention. all cars have it
with EFI.
does that help.

key factorys, ASD closes, for 2 seconds.
crank with no errors (scan tool shows errors after 5 seconds cranking)
if that works the engine does start.

ask for more tests, i have 3 more that find any bad start.

Ford focus will crank over for 5 seconds before starting


You may be on the right track, but I doubt it is an injector.
If one of the injectors were leaking the car should run rough when it finally starts and the check engine light would probably come on.
It could have a faulty one way valve in the fuel pump in the tank which would let the fuel pressure leak back into the tank. Could also have a problem with the pump relay.
I would check the fuel pressure with a gauge before and after startup next.

1987 jeep cherokee 4.0 Starting Issue engine cranks over but won't start- will start and run if primed. Will restart ok but if left setting will not start again. Changed: Fuel Pump Fuel Pump...


Check your temp sensor. if it's out of range it could be sending incorrect readings to the computer. Also check the white ceramic block on the drivers side fender back near the brake cylinder. It is a resistor that affects pump pressure on start up.

I need all the diffeent firing order for gm 3400 2000 I have a back firing issue that won't let the van start?


it sounds more like the crank sensor is bad. when crank sensor has failed or is failing, certain timing problems will arise. the engine may start but shut off in a few minutes or seconds of operation. more than likely engine will not start. it controls timing, engine backfire, no spark or pulse at injectors, car will stall when stopped. heres the firing order: 2-4-6 front from left to right
1-3-5 rear left to right hope this helps !! go here for a diagram-- http://autorepair.about.com/library/firing_orders/bl-fo-6417.htm have a very good day !!

1990 toyota celica fuel problem. It appears to be flooding. When cranking, if it has been sitting for a while, it fires for just a second, and then dies. When the fuel pump is unplugged, and engine...


start with trying to start the car with your foot hard on gas pedal, all the way to the floor this will stop fuel flow on start up its called clear flood mode. as the engine starts to fire and run ease off the pedal until it idles, it may take some time to run smoothly. if it doesnt run or stalls after a short time and then will not run i would try a ECU engine control unit as it supplies the earth circuit to the injectors, may be thats whats holding them open or they are dribbling badly and require overhauling

Car starts and cuts out after 2 to 3 seconds. fuel


When the ignition switch is turned on the pcm turns on the fuel pump by energizing the fuel pump relay. The PCM keeps the fuel pump on as long as the engine is cranking over or running.It does this by recieving pulses from the ignition module. If there are no referance pulses the PCM will turn the fuel pump relay off in 2 seconds with the ingnition on.

Most models also include a secondary control path through the oil presure switch witch will turn the fuel pump on after it detects oil presure.cranking time will be longer if the fuel pump doesn't recieve current until oil presure switch contact is closed.

2002 malibu wont start


check for a bad crank sensor for this controls the timing of crank shaft. and sends info to pcm. it will cause no spark or pulse at injectors.the engine may start but cut out in a few minutes or seconds, of operation. have the car scanned for the problem code, if no scanner, any auto parts store will scan for free. good luck !!
