I just finished doing 5spd swap and my car does not crank at all. I know the starter is good, because I bought a new starter from autozone and hot wired starter to see if it will turn. I checked all the wiring with my multimeter, check the voltage and resistance. Black/Red wire that goes on to the starter connector, does not get any voltage to it when I have key in start position. So I checked all the fuses and wires related to starter circuit, and they were all good. I also have my neutral safety switch wires hooked up right, so ecu sees the tranny in neutral all the time. I have aftermarket alarm installed on my car, which I bought the car with. Can aftermarket alarm disable ignition system? Note that I have no manual for the aftermarket alarm.
thanks in advance.

look up the make of the alarm system you have installed and see if that feature is built in.

if anything disable the alarm system just to eliminate that as a factor.
make sure all grounds are connected, if any were dis conencted.

did you change the flywheel and yes an aftermarket alarm will cause your car not to start if it's acting up

The ecu has nothing to do whether your engine will crank or not. Hell you can pull the ecu right out of the car and the engine will still crank, it just will not start.

Do you still have the inhibitor relay wired in?

I am not sure you understood that...I wired the park/ neutrall switch wires together so the ECU knows its in Neutral....and what inhibitor relay are you talking about?...as for the flywheel? what would that do for it to not crank...the engine is not seize nor tranny is stuck..I ve cranked the starter from the battery and it cranks so that is fine...Ive checked the voltage meter from the ignition to the starter relay...checked the wire harness too..its fine..I think it has something to do with the alarm...thanx for the imput guys keep them coming...its a little frustrating at this point....I think I might have to rip out the alarm to pinpoint any discrepencies to this delima

Check your grounds

Ive checked the ground wires to the tranny...the engine, the one by the IM,...uhh...what else?...

You need to look at a wiring diagram of the starter circuit. You will see that the ecu and the PNP switch on the tranny have nothing to do with energizing the starter solenoid.





What starter realy are you talking about?

In an AT you have an inhibitor relay wired between the ignition switch and the starter solenoid.
In an MT you have a clutch interlock relay carrying out same function.

Wow...thanx for that clearafication. I will try to reference that....much appreciation.

woo Hoo!!!! yeah!!!! I got it crankin....1 more step for it to be on the road. It was a connector taped up by the positive terminal.it wasn't connected.I guess its an honest mistake when there is alot of connectors leftover hangin for the automatic.What a dumbarse I am....someone hit me with the hammer...

You're right about ecu has nothing to do with cranking. I was trying to say that starter circuit will be always open if tranny is not in park or neutral.
