I have a 93 Bonneville and the engine is as strong as it was when new. I started the car and let it warm up and put it in drive, I moved about 15 feet before the engine died. It still won't start to this day. The fuel system is good, it has fuel pressure,. So next I checked for spark - no spark. i got new ignition module and coils
GM computer crank and camshaft position sensors and even the computer chip in the key is good. Countless hours with wiring diagram and voltmeter. And there are no codes in the computer.

I desperately need help, like I said above the car ran like new and then nothing . It'* like somebody flipped the power off switch, I don't understand it.

hellp plz

Sounds like you changed all the required ignition components except you didn't mention plugs & wires. Assuming you also checked/replaced the plugs & wires let'* check for power going to the ICM. You should have 12 volts at the pink/black wire going to the ICM. With the key in the run position 1st check for power between the pink/black wire & the negative battery terminal. Next check for power between the pink/black wire and the plate that the ignition module mounts to.

will no.. same plugs and wires but i got no spark at the coils

have 12 volts at the pink/black

but the all black/ground has no ground so i jumped a new ground to it to try that out but no luck

i put new crank and camshaft position sensors in about a year ago i hade the same problum then.. but thay did not fix it so i keeped the old one
it was the ignition module that time [got one out the junk yard]

so now i got same prob so i ran down to the junk yard and got two good looking ignition module, but none of them worked so i pulled out the old crank and camshaft position sensors from last time[thay where good then]and put them in, no luck

at this time im getting desperate so i start testing everything but still no luck

i have
3 ignition module
like 12 coils [all good]
2 crank and camshaft position sensors [each]
2 computer
2 maf sensors

and none of them work......im gona get the 3 ignition module tested just my luck there all bad
wish me luck i need it

The wiring diagram I have doesn't show a black wire going to ground. You'd better remove that jumper wire. Can you describe exactly how you're checking for spark.

the old screwdriver to ground test and with a spark plug

its dead you can put your tongue in it its so dead

i remove that jumper wire.. on my wiring diagram the black wire is next to the pink/black wire with a ground symbol but the black wire is not in the same spot in the car
i dont have any ground in that plug

advance auto parts wont test them,, is there any way to test a ignition module ?

Autozone tests the ICMs, but it is not a definative test. It could be bad, but test good, or the other way around. The best way is replacement. If you know anyone who has a 3800 you can swap it out of for a test would be the cheapest. A junkyard is a possibility.

The computer chip in the key may be good but there could be dirt in the key switch.
Are you getting a security light when cranking?

i tested the key with a small pice of tape the car wont crank with the tape on the key chip

ill check security light when cranking

but it was running then it just stoped

im gona get a new ignition module
the ones from the junk yard must all be bad

how bout checking the Battery cables to make sure they are tight and have NO corrosion behind the boots
