Gotta breathe life into her...
Ok, here's my situation:
'84 944 that wont start. Plugs are clean Engine condition is unknown I gotta move it across town before I turn the keys of the Apt in She barked, coughed, and damn near fired when I shot either in the pistions. She DOES turn, and almost fires On another forum they had said that these machines were mechanical pumps, and if that sat even for a short amount of time they had to be primed and/or push started because for whatever reason fuel wasn't getting to the block. This individual said that they'd short the pump back at the fuse box, but could not remember which fuses (numbers, etc.). Can anyone comment on this? I'm on flat land so I'd like to avoid the pain of the trailer. But if I must, I must. Thanks in advance for your assistance. |

It's an electric fuel pump, I don't know what that business about priming it is about. You'd hear it whirring away if it wasn't drawing fuel, it's underneath behind the passenger rear tire area.
Here's how to bypass the DME: http://www.clarks-garage.com/shop-manual/fuel-05.htm

If it fires on ether, you are getting power to the DME, and you have a spark. You need to find out if you have fuel pressure or not. If you do, next thing to check is if the injectors are pulsing. If they are, it's leading to no signal from the refrence sensor, which controls ignition timing.
You have to approach these problems very methodically. Start with the basics, eliminate one thing at a time. |
