I am chasing an intermittent no start on my 88. It is so intermittent that I have been able to get it to fail when I have had any tools to test anything.
When I turn the ignition switch to the start position nothing happens. No clicks or noises of any kind from the car.
I doubt that this problem is related to the starter because normally the car starts fine. There is not any drain on the rest of the system like the starter was drawing too much power.
At first I thought there could be a problem with the neutral start switch but since placing the car in neutral doesn’t change anything I have kind of ruled that out.
The alarm system has been disabled at the lock cylinders so it can not arm. I have considered completely bypassing the starter interlock with the alarm but that would require more than one wire to be disconnected and I don't want to mess with the alarm system anymore than I have to on a wild guess
I have tested every known body and frame ground and ran redundant grounds from the engine block to the body just to be sure. Attaching jumper cables to the battery does not change anything.
When the car fails to start the car has power everywhere but the starter and the fuel pump. The windows and lights work and the DIC is working fine. Heck, the radio works fine at keeping me company.
The only thing that seems to be unusual when this happens is that the volt gauge does not read 12 volts immediately; it seems to start out at 8-9 volts and slowly rise to the 12-13 volt range.
After about 5 to 10 minutes of turning the ignition switch to the start position the car just starts up fine. This has happened 3 to 4 times in the last year. I am running out of ideas to try.
Any suggestions would be appreciated
