Re: Start issue
It Could be other heat related issues as well. fuel pump relay, bad multec injectors, icm
. Remove the fuel pump relay and inspect the wiring, some obd1
Have a test wire at G of the aldl to apply power directly to the fuel pump This would not eliminate a issue at c100 connecter. Using a noid light to check for injector pulse, a spark tester to check the icm and phmimg the injectors while the engine is warm are all good diagnostic checks .
