E320 no start
Hi All,
After I did the head gasket replacement, fired up the 94 E320 (M104.99) and it ran nicely. Took it for a drive -had two several second bouts of high reving, but they seemed to correct themselves. It worked well for a few miles - couple of short trips around town. The next morning after rain and cool temps, it started hard and missed badly. Not drivable. After the weather dried up and warmed up, I tried again and had the same result when I could get it to run at all. I checked the engine harness (which I already suspected) and it was full of dust and bits of cracked insulation as I expected. I completely rewired the harness. No I get no start. It cranks but not in a good sounding way - almost like it's restricted somehow, then after a couple seconds it stops cranking. I can pull the injector wires off and it sounds fine when cranking continuously, so I don't think it's mechanical. I have re-checked my harness wiring with a meter and everything tests good. Coils and injectors ohm out within spec. Fuel pump fuse is good, all other fuses look good. Can't detect any shorts in my wiring job. I did delete the air pump coil connector, as the pump was removed it from the system, but can't see how that could be in play. I have not yet looked at the ETA wiring. Could a bad ETA harness cause a no start like this? I know that it could be the cause of the surging I had on the first test drive. Any other ideas? |
