: Another Wont crank issue

Ok. So I just studed the motor and replaced the head gaskets. Car has been down for 4 or 5 months...i lost track. Anyway, I've got it back in the car and everything is connected. I get in and put the key in the ignition. Dash lights up and dings at me. Security light stops flashing when i put the key in, but the digital readout say Security system problem. Car probably wont restart. I have no idea where to start. Any ideas? I did make sure everything was grounded as well, and i can hear the fuel pump prime. It has a brand new battery, and alternator as well. I'm stumped.

Try the other key?

There is a wire around to eliminate the security feature.

I only have one key. Isn't there a re-learn procedure for programming the key fobs? my fobs aren't working either. It says Problem with theft system, car probably will not restart. I turn the key and ALL the lights in the car go off. I can hear several relays click under my feet as well. I was trying to avoid the wire around. This thing did work when i took it apart.:mad:

Make sure the contacts on the resistor chip on the key are clean. Maybe spray some WD-40 in the ignition switch to help clean those contacts off as well. Put the key in and wiggle it around before trying to start it.

ok. Well, i fooled with the key and did the re-learn to no avail. I am going to test the starter to see if it is bad or locked up, but i still think something else is wrong.

Something else is definitely wrong if it didn't do this before. Check your wiring.

I haven't read the whole thread. But try this:

Get a helper to hold the key over to the "crank" position while you hot wire the starter. Hot wire the starter by un-doing the two wire connection the comes out from under the intake manifold. Jump the thicker (purple I think) wire to 12V+ and the engine should crank, and start.

I had a weird problem like this with my '98 once and I did this one time and haven't had an issue since. From an electrical standpoint, it doesn't make any sense. I think somehow I must have had a stuck relay or something.

If it doesn't crank by jumping that thick purple wire to 12V+, the problem lies in the harness that attatches to the starter, or in the solenoid.

Note that disconnecting that starter connector also disconnects the knock sensor, so if a code is thrown that'd be normal.

Oh thats what that sensor is between the cylinder 3 and 5. Always thought it was temperature sensor(In airplane it would be CHT, cylinder head temp.) But 93-94 Northstar knock sensor are somewhere else.

Thanks guys. I will hopefully be able to get to this sometime today. Between the rain and being sick i haven't had a chance to mess with it much. I have been saying the last few days that i thought it could be something just hung up from sitting so long. Damn electrical...

Ok. Its fixed. Just a note to anyone working on these things for the first time. The Negative battery cable has to connect to the front of the block. No ground = no start, no fuel, and a theft security problem. It was my ground. I knew it was something stupid. Now all i have to troubleshoot is the p0300 misfire code. It is missing pretty steady. I'll look at the wires again and make sure my plugs are all in right. Probably need to make sure none of them are closed up....which would mean my time chain is a tooth off...hope not.

Pistons won't hit the plugs if they were off by 180 degrees. The piston only comes up so high and the plug never changes position above the piston. Valves are another story.

i think its an intake leak. i reused the gaskets and they look pretty crushed. I'll replace em and see if that clears it up. All the wires are fine and the rattling has ceased.
