My 96 gc limited died and wont start..fuel pump is working. Replaced crank sensor, cam sensor,coil,plugs and wires,still nothing.

Sounds like a security system problem. Check your ASD relay and fuses.

drob9069

Ive put new relay in.. Im gotting 30 volts from coil, and 5 to 12 to the spark plugs. Should that be enough to start it?

drob9069

Would the security light be lit if it was the system..because its not...might be a dumb qiestion but im running out of options

dave1123

Uh, no. The coil should put out around 30,000 volts and the voltage at the plugs shouldn't be more than 5% less. Change your coil.

Sorry, I reread your post and see that you already have done this. Take out a spark plug and see if you have a good hot spark while cranking. If so, pour a little gas down the throttle body and see if it fires up. If it does, you've got injector problems, either electrical or fuel delivery failure. Is this a 4.0 or a V8? Even though the pump is running, check the pressure at the fuel rail or throttle body. The pump should only run long enough to bring up pressure prior to starting. If it's running constantly, you're not holding pressure.

Your engine isn't running long enough to set a code.

Either that, or he damaged the volt meter when trying to measure the voltage at the coil.

Ive put pick up coul and cps

Go back and check post number 5. Some guys posted while I was typing.

drob9069

It isnt sparking..ive poured gas down the throttle body it does nothing..the fuel pump jus runs for a few secs like it should..maybe i got a bad coil from the parts store..wont be the first time..im goin to get another one and try it..if ive put a cam sensor crank sensor the coil should be the only thing left right? It jis died on me while i was driving. Could the coil jus go out like that?

drob9069

Its a 318

dave1123

Yes, the coil can go just like that. However, for most people it's the crank sensor, which is why you looked at it first. It would be a comedy of errors if your replacement coil was defective as well. The fact that you have voltage to the coil seems to eliminate electrical problems before it.

drob9069

So you think i should go ahead and put another one on it?

drob9069

New coil didn't fix it.. How do I reset the security system?

dave1123

I honestly don't know enough about it to tell you for sure what to do, so I'm going to pass on this rather than lead you astray.

drob9069

If it was the security system wouldn't you think that it would cut complete power to the coil? And thanks for your help by the way
