Are there any issues with the 86e TPI?
I recently bought an 86E TPI and its got an interesting set of issues, especially with idle. Id like some opinions and input to start planning a repair route please.
What causes a Chevy Corvette 86 TPI to stall?
It never stays constant. Its stalling under a minute after start up, and it will stall once the idle drops if I rev it while its in P. Also stalls sometimes when shifting into gear (from R to D). I tried changing out the fuel pump with a new one, but then it would not start.
Can you have compression, spark, fuel, and air but not go?
You can have good compression, ignition, and fuel and still not get a 2 cycle to pop off and run. If you have a major air leak into the crankcase, you will never get it to start and may never even get it to pop. Make sure there are no air leaks around anything that attaches to the crankcase and that the top and bottom seal are in place.
What causes the fuel pump to not start?
The fuel pump is running and delivering normal pressure to the engine But, with all that working your engine still will not start. So, the most likely cause, is that the fuel injectors are probably not opening. The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors.

What makes an engine not start or run?
All engines require three things to start and run: spark, fuel and compression. If any one of these is missing, your engine will not start. The fuel pump is running and delivering normal pressure to the engine
What happens to your car when you idle?
A rough idle will result in intense vibrations forming whenever your vehicle is stopped with the engine running. Since less air will be going into the engine during its idle state, the car will react by shaking profusely.
What causes idle surge problems on Foxbody 5.0?
Low voltage (below 13.2v required to keep the battery charged) can cause a plethora of problems. Underdrive pulleys may also aggravate the situation. Note: If you have a 3G upgrade, be sure you have a ground upgrade (4GA min.) from the block to the chassis.
