Customer Question

JA: Thanks. Can you give me any more details about your issue?
Customer: Engine won't start or turnover. Starter won't engage. turn the key and nothing. We've checked fuses & battery. We think we have a grounding problem. OBD II sensor say's it can't communicate with engine. Thanks, Steve

Hello, Eddie here and I will try to help. did you check your big amperage fuses out under the hood? When you turn the ign. switch on, does anything work? like power windows if it's got it? or radio? or anything associate with the ign. switch? you get NO dash lights right? not even ABS or BRAKE light?

Customer: replied 1 year ago.
we checked the fuses. Radio works. head lights work. No dash lights and no starter
Expert:  Eddie replied 1 year ago.

Alright, I believe it is a wiring short, or open in the harness somewhere then if the ignition switch does power up the radio. But to say where without being able to look at the vehicle would be difficult. I will opt out and if any other experts have a suggestion they can respond then. Thank you.

Hello Reggie here assuming this all worked prior to your engine swap i agree ground wire is likely it, you have 3 i believe at right rear cylinder head and some at the thermostat housing, have you checked them and gone back to your main wire

Another possibility would be a blown fusible link have you checked voltages at all fuses with a voltmeter, you cant look at a fuse link and tell if it is blown

If you will check the voltages, i will be monitoring my inbox i will walk you through finding this right now
