buggy will not start

94Dodge Truggy · 02-21-2007, 08:00 PM

Well, here it is. I have been doing alot of work on the buggy including welding. I recently left the key in the run position for a week while working on it. The batteries still have plenty of charge, but it will not start. I have spark but no power to the fuel pump or fuel pressure. Fuel pump is good. I am thinking that from welding and not disconnecting the battery and having the key in the run position that I have fried the computer

. The relay and fuse for the fuel pump are fine. Can I have the computer tested? I have a computer for the same year of truck, but it is for a 318 5 speed and my truck is a 360 auto. The truck is a 1994 dodge ram. Anybody have any knowledge on these trucks? Thanks, scott.

that sucks man, does sound like you fried something... check ALL of your fuses first... if im right, dont you have some under the hood, in a compartment, those big ones?

hopefully a fuse would have caught the surge.

Like Mike said , check and re-check all fuses and relays and then I would put that 318 ECM in it and see if your pump works , it might run that 360 and it might not , but my guess is that it will at least communicate with the pump. Also disconnect the battery for a while and then reconnect and see what you get . Sounds almost like it went into a safety mode to save the pump and injecters?????? just guessing ..... it is a DODGE and well

Sounds like it is the ecu. I did try disconnecting the battery for 1/2 of an hour with no luck. Gonna try the backup ecu and see what happens tonight:o . thanks for the info.

first line of the instructions for EVERY repair in a haynes or chilton's manual is what? "disconnect the battery."

i don't always do it either, unless i'm welding on a vehicle a bunch... then i do. I bet you will from now on too.
