Greetings all,
My car has an Electromotive HPV-1 crank fire ignition that seems to have given up the ghost. The car will run for a few minutes (badly - backfiring out exhaust stumbling) and then die altogether. No spark. When it's stone cold it'll rinse and repeat. It doesn't run long enough to have engine heat be the cause, so I fear it's a component inside that's shorting and causing it to fail. The circuitry is all potted so I can't easily see if there are any fried bits. I've gone through the install countless times, new crank sensor, ground wires up the wazoo but no love. The company is long gone, so factory service NA. Does anyone know of a repair or replacement service for these, is it worth it, or should I chuck it all and start over? I honestly don't know if the distributor drive gears are still in the engine. It was all built by Fat Performance in the '90's, but they seem to be gone too. TIA, -C |

Post a pic of what you have, I’ve never seen a setup for a 4. I picked up an extra for a 6 in case once of mine craps out, but I’m really leaning towards finding something more current to replace it with even a more current electromotive product…

The TEC units were designed to also run fuel injection, and may need some of those inputs (MAP, etc) to work properly. Not to mention that EM is long gone so serviceability is non existent no matter the age of the unit... I'm okay with programing but not expert by any means so flailing away at a laptop doesn't exactly excite me. I may just have to bite the bullet and buy a modern system such as the PE3. |
