bapman Posted March 10, 2005 Share Posted March 10, 2005 I have an 82 4x4 wagon, 4spd d/r that will not start. The starter is turning the motor over but there is no spark from the coil or power to the fuel pump. I have replaced the fuel pump control unit, and the coil. I tested the fuel pump directly from a battery and it worked. I am unsure of what to check next. Any insight would be greatly appreciated. Link to comment Share on other sites More sharing options...
northguy Posted March 10, 2005 Share Posted March 10, 2005 Did you check the fuse box? Any fusale links blown? Link to comment Share on other sites More sharing options...
TheBrian Posted March 10, 2005 Share Posted March 10, 2005 Did it just start acting up, or is this a restoration project? I'd say get out the voltmeter and see how far the power reaches. Ignition coils can be tested by measuring the resistance across their terminals. You'd need to find out which terminals, and how much resistance is spec.

bapman Posted March 11, 2005 Author Share Posted March 11, 2005 The fusable links and the fuses in the fuse box are ok. Anywhere else to look? And yes it has been an ongonig problem. I while driving i would lose power and it usally would die, able to restart in a minute or two. Link to comment Share on other sites More sharing options...
Skip Posted March 11, 2005 Share Posted March 11, 2005 my check mark goes beside the ignition module in the distributor no pulses from it and the FPCU will not run the pump Link to comment Share on other sites More sharing options...
bapman Posted March 11, 2005 Author Share Posted March 11, 2005 Is there any way to check the ignition module? Or easier to just replace? And is this something that I could get at a wrecking yard or should buy new? Link to comment Share on other sites More sharing options...
Skip Posted March 11, 2005 Share Posted March 11, 2005 you could test it with the aid of an oscilloscope or possibly with an older style "dwell tach" set in the dwell mode As for replacement, boneyard or CCR Inc. http://www.ccrengines.com/ possibly Your 82 is kind of an odd sort out The FPCU it employs went out of fashion soon there after. I am sorry I can not answer if a newer EA81 distributor will function properly. Emily or Shawn at CCR may be able to. If so there are two types Nippon (2 wd) and Hitachi (4wd) Operating principles are the same but the advance curves are different. Link to comment Share on other sites More sharing options...
bapman Posted March 13, 2005 Author Share Posted March 13, 2005 I got a used distributor from a wrecking yard for $45, and it RUNS!!! Thanks for the info about the ignition module. Wasn't even considering that as a possiblity. Link to comment Share on other sites More sharing options...
bapman Posted March 13, 2005 Author Share Posted March 13, 2005 Thanks for the tip Skip. A $45 distributor from a wrecking yard gave life back to my wagon. Link to comment Share on other sites More sharing options...
Skip Posted March 13, 2005 Share Posted March 13, 2005 Glad to hear it was relatively inexpensive fix, you're most welcome. And again welcome to the good ship USMB Link to comment Share on other sites More sharing options...
Cougar Posted March 13, 2005 Share Posted March 13, 2005 Good call Skip on the diagnosis. One easy test that can be done to see if the ignition pulses are coming from the distibutor is to place a test light probe on the minus side of the coil and clip to ground. While cranking the engine, the light should pulse with the ignition signal if things are ok. If the light just stays on then the problem is in the distributor area.
