Hello, is it manual or auto transmission?
Thanks, ***** ***** will need to do to begin is check the grounds and ignition and battery power at the ecm. I'll post how the pins are configured and location below. Let me know what you find and we can work further.
A1 & A2 groundsE15 & E16 12 volts
Thanks, ***** ***** happen to have a voltmeter to ohm a1 and 2 to ground? or can you check the reading from a confirmed good ground to e15 and 16?
Great, let me know what you find and we can continue
Great, do you happen to have a way to jump a2 to ground and then try to start it.
Thanks, ***** ***** a direct feed frm the b+. IT runs to the middle fusible linnk on the junction block on the firewall. What you can do is check it before and after the fusible link. It's an orange wire that goes to a gray fusible link.
Thanks, you'll need to cut out the old fusible link and install a new one. Most parts stores will have them, you want one that's 4 sizes in gauge smaller than the orange wire. You could also just install an inline fuse holder and a 20 amp fuse. This should resolve the problem. If it does not you'll need to ohm the aronage wire from the ecm to part before fusible link to see if it's possibly partially broken. In most cases like this it's the link
