I just picked up a 91 dodge dakota that one of my friends spent a bunch of $$ on replacing almost everything. plugs, wires, coil, distributor, are all new. I saw posts on corroded wiring by the battery so I dug into the harness on both sides of the truck actually but haven't found any corrosion inside the harness. Had a little on the grounds on the body so cleaned those up. I noticed while cranking that the tach needle jumps so I'm thinking it's recieving signal from the pick up coil in the distributor. I pulled the computer plug and pulled the computer out, found a mouse nest inside so cleaned it out. I'm not sure if the nest had been in there before it quit running or if it could be the reason I have no spark. There is a heatsink inside that the nest was built around so it would've definitely made it get hot if it was in there while running I'm sure. I'd hate to buy a computer though and find it's not the problem. Oh, also checked codes and only get 12 and 55. Is there anything else I should check or is a new computer in order?

Do you have fuel pressure?

 

[ImperialCrown]

Even with good fuel pressure, if the injectors aren't squirting, you still won't have fire.
Will it fire up briefly with a spray of carb solvent into the throttle body?
Do you have spark at the spark plugs while cranking?

I'm having the same problem what is the code 55

It is end of codes. If you only have 55, there are no codes to display.

As an addendum - if you ever have a question on the codes because you haven't obtained a factory service manual yet, Dakota Trouble Codes (dakota-truck.net) has a code decoder. Just put them in with a space between each code and it'll spit out what they are.
