Recently removed and replaced right head and ac condenser fan. After 10 minute drive, Ignition coil cyl 7 fried. Found DTC’s P0207 cyl 7 fuel injector circuit, P0357 cyl 7 ignition coil circuit, P0358 cyl 8 ignition coil circuit. I have replaced cyl 7 injector, cyl 7 ignition coil, cyl 8 ignition coil, injector/coil wiring harness, checked wiring from black terminal on PCM, to connector at the injector/coil wiring harness. No issues found. Codes return when engine starts.

The oil pressure gauge doesn’t rise on 1st start, I have to shut the engine off and start it a 2nd time for oil pressure to gauge to rise.

The truck will crank over but will not start I’ve changed fuses, relays, crankshaft position sensor, tested spark and only have spark at the ignition coil and not on any of the cylinders have spark. What could be my issue what could be the cause

Is there any reason why my oil gauge stops working after being on the freeway exiting and coming to a red light?

Crackling song once reved over a certain rpm
The oil was low and thin

The mechanics said there were no faults after diagnosis. They did an oil change and it ran. Got it back home and it won’t start. It has 3/4 of a tank. Could it be a bad relay? Can it be bypassed?? Help!

I have wiring problems with the green and orange wires that run injectors and coilq
