Thanks for letting me in.
I have a Chevy S10 4WD no fire when cranking over, it will start eventually after working key from run position to cranking position a few times, I put a timing light on the coil wire to see if it was firing it only flashed 1 time when cranking I replaced the ignition switch, distributor, fuel pump, crank sensor, and relays I'm stumped, It will start up with starting fluid and once it gets warmed up it will start every time except when it sits overnight, fuel pump pressure is around 60psi. when it runs no missing runs smooth, I don't think its plugs, I'm beginning to think the spider injection system is going bad?
