TRP951

I started my car to move it last night and it started up no problem and then when i tried in the morning nothing it cranked but the fuel pressure gauge shows no pressure? Any ideas?

pump, pump fuse, DME relay... Maybe some others, first try and jumper the fuel pump and see if you get any pressure if you do then you can most likely call it the DME relay.

I checked the fuse and its good, also i have a spare DME relay that I tried and nothing, The fuel pump is a new walbro one but i will try to jumper it to see if I can get it to work. What terminals do I jumper to run it?

Also keep in mind it ran great pulled out of my driveway pulled in shut down did nothing and the next morning nothing.

Okay: 30 is directly from the battery and 85 is powered when the key is on.

87 is the DME and injectors and 87B is the fuel pump. what i would do first is just connect 30 and 87b but dont try to start it cause it wont, and just check your fuel pressure, if you have it then the realay is probably bad. but to make sure its not your ignition switch, then just connect 85 and 87b and when you turn the key to position II the pump should run if so, the your realay is bad.

Then just run a second wire from 85 to 87 to also power the DME and injectors and you can then drive temporarily. Be very careful when hooking the fuel pump (87b) directly to 30 (battery) because key or no key the pump will keep going so if you busted a line or something... yea not good!

ok the pump gets power and when I put a jumper for the relay in the car starts connecting terminals 87,87b and 30
