1996 Plymouth Voyager 3.0

Car was not successfully starting each time. Now it doesn't start at all

So I installed some new parts:
Starter
Neutral safety switch
Starter relay
Ignition switch

Still no start.

If I pull the starter relay, put the key in the RUN position and jumper sockets 87 and 30, the starter spins and the car starts.

I put on an ODB-II code reader and there are no codes showing.

What else should I try?

Thanks

Ok first check resistance between term 85 and 86 on the relay itself should be 70 to 80 ohms anything else means you got a bad relay warranty it.
Now check term 85 and see if there is continues power to it it not then find short in wire and fix. Let me know what you find and we go from there.

Thanks racefan966

Starter relay:
Resistance across terminals 85 and 86 is 72 ohms, so it's ok.

PDC cavity for starter relay:
Cavity 30 connected to ground shows 12.5 volts - ok.
Cavity 87 to starter solenoid shows continuity - ok
Cavity 86 shows no voltage to ground with key in START position - not ok.
Cavity 85 shows no continuity to ground - no ok.

Park/Neutral switch:
Center pin to transaxle shows continuity in Park and Neutral, no contuity in Reverse and D - ok

So it looks like short or open to terminals 86 and 85.

Any suggestions on how to track that down?
Thanks.

I replaced the electrical ignition switch on the steering column, not the lock cylinder.

Well it sound like the neutral saftey switch may be bad. As for the power to term 86 that comes from the ignition switch. It comes from the switch with a yellow wire to a 3 amp fuse (#10) in the fuse box and then goes to a yellow/red wire. Then there is a 9 amp fuse that is the run fuse and it goes to the relay via a white/black wire to the power module and then comes out of that tan and to the relay. So check the fuses to make sure none are blown and go from there.

Okay, found the problem.

I started following the yellow wire from the ignition switch and the first thing I came across was a relay from an aftermarket alarm system which had been spliced into the wire. One of the connectors had fallen out of the relay.

Thanks a lot for your help racefan966.
