I am in the middle of moving to the UK. The Air Force has already picked up all of our stuff. 2 days ago I tried to start my car and no luck. It's a 76 and after relacing or troubleshooting everything, it's still not starting. I bit the bullet and bought a vacuum pump from Harbor Freight to check out the MPS. It isn't a complete fail, but it leaks down from 20 to 14 lbs in < 4 min.
List if things I've done. New vacuum lines, rubber intake sleeves, injector seals, fuel filter, spark plugs, head temp sensor. Checked fuel pressure, injector function, TPS adjustment. I have the 123ignition distributor with new cap and rotor. I have to ship this car in 10 days or less. Obviously it needs to be running. Does anyone have a known good 2.0 compatible MPS I could borrow/rent/purchase right now? I'm in Panama City, FL. Given the weather, something closer to me would probably be better. Other options could be a good running set of carbs and intakes or if someone has a plug n play microsquirt setup sitting on the shelf. Any help is appreciated. |

I agree that the MPS should be good enough, but I've gone through the whole engine and I'm running out of options. The car ran reasonably well on Wednesday. It was a little tough to start. I assumed it was the relatively cold weather.
Thursday morning, no luck. It sounds like it wants to fire, but just won't quite get there. I am getting spark and some fuel when cranking. I'm running non ethanol fuel. The first thing I checked was the TS2. It tested within range. Eventually even checked the TS2 connection at the ECU. I swapped in a new one that checked out, just in case. I'm at a loss for the moment. Hopefully I missed something simple, but can't rule out the MPS after checking everything else. |
