Try to make this quick
1999 Suburban CK1500 4x4, all stick but lift kit with almost 250,000 miles.
I had leaks so I replaced oil pan gasket, oil pump, oil cooler lines, filter adapter and timing cover (I did not replace timing chain or gear), Y-Pipe donuts, water pump, knock sensor
Two days before doing this I got random misfire in cylinder 2 and then in a different cylinder following day. I was going to tackle that after this big leak project was done.
I got everything back together and now it won’t start. No spark at all. I’ve got 61psi of fuel pressure.
I’m extremely pressed for time as I’m borrowing a garage and I’m already 2 days over my expected leave date.
I replaced:
1. crank shaft positioning sensor.
2. Coil
3. Stupid over priced ICM
3. Knock sensor and soldered new harness.
still no spark. I’ve got 12v at cps and it’s ground is good. I’m currently cleaning the engine to frame grounds, but I think they were good.
I saw the 7 page trouble shooting posts.
I get to the point where it says jump a whole bunch of wires and use a special tool in a kit and that’s beyond me
It’s just weird that it always started and I replaced oils pan and timing cover then I get this problem.
