The symptoms of a fuel problem are1 no fuel to the engine 2 low pressure ot the engine. What you describe indicates thet the pressure regulator in the fuel manifold is not holding sufficient pressure to run the motor. Best to habe the pressure checked of both units befor spending dollars on what not be faulty

SOURCE: I have a 1997 Chevy Cavalier with a 2.2 Liter

Sounds like either the ignition module and or a coil pack is the culprit. I dont remember what year they changed it but if your is the one where the coil packs/module are located on the back of the motor they are a little tricky to get to. You need to remove dog bone mount and replace with a tool that will pull the motor forward so you can gain easier access...good luck. Hopefully yours are right on the top where they should have been since day one... :-)

SOURCE: wont start has fuel and has spark

RC ralston
Your problem is a leak in the cpi pletium most likely the pressure line has a leak
had same problem with mine $45.00 PRESSURE LINE KIT AND $15.00 GASKET FOR PLETIUM and 2 hours labor problem sovled.
You can remove vortec cover and remove air regulator to look inside pletium. I had gas vapor on driver side . that is where fuel lines are. fuel regulator is on passenger side. turn key on and look in hole and see where fuel is spraying. taking pletium off you can again turn key on and make sure where fuel is coming from.

SOURCE: 82 corvette crossfire injection, engine

Please go to the crossfire injection forum to get some straight answers to the 82 corvette CFI system and how to troubleshoot it properly. There's a lot of misinformation given here, so much so, I don't know where to begin.

One thing is, the 82 corvette CFI does NOT have a MassAir Flow sensor system, it uses MAP and O2 mostly. The CTS sends a signal to the ECM telling it what the temp of the motor is and in turn the ECM controls the amount of fuel being dumped. On the older (orignal) CTS sensors, they have one wire and takes its ground from the threads. If any coorosion takes place, usually the CTS will report a cold engine and request lots of fuel.

To repair this issue, install one of the newer style CTS sensors that have two wires, one for signal and the other is ground.

Fuel pressure and vacuum leaks on any CFI motor play key roles. Set the FP to 14-15psi measured inbetween the TBs. The regulator is located on the rear TB and must be slightly moded to make it adjustable and can be done in a few minutes.

Car idles fine, but sputters, bogs and dies if gas pedal is pressed.


new spark plugs this decade. (a tune up?0
the filter is part of all 60k tuneups. letting it clog wrecks good pumps.
my wild guess, its lack of fuel flow, do to old filter.
or low fuel pressure.
car is identical to a Corolla. so is not unique or rare as some Geo cars are.
the cam belt not changes, invites valve kissing piston tops. BOOM
end of engine. (costs more to fix then worth of car)
the word is bogging, my engine bogs
if if bogs WOT (wide open throttle) and dont catch up < ITS NOT THE TPS. ever.
tps bad causes short bogs, called hesitations.
The map sensor , is what measure air flow and the ECU matches fuel to this air flow.
my guess, is it does that, but fuel pressure is like 15PSI, bad.

When i start my mach 1 it runs fine when i use it for 5 to ten minets then when i go up a hill it bogs down and doesnt move and will die


Sounds like either your fuel pump and or fuel filter is bad. Change fuel filter first and try the hill. If it still bogs down sounds like fuel pump is almost ready to die. Get a pressure test run on fuel pump.

If above does not work then it maybe maybe your catalytic converter. Have it checked. Good luck

Why does my car bog down and wont accelerate up a hill?


Usually a sign of a fuel problem, either too much or too little.
Too much could be several problems including a clogged air filter, too little could be a weak fuel pump or other issue.
A mechanic would check fuel pressure and air flow first.

I have a Yerf Dog CUV Rover that will crank but runs like garbage. If you give it more than quarter throttle it will bog down and most of the time shut off Please help


Fuel system faulty. Not to hard to find the problem. Check in this order.
  1. fuses
  2. fuel filter
  3. fuel pump relay
  4. fuel pump, even it you hear it running, it can be too weak to run an engine at speed or under load.

Does it bog down and die, sputter like it's running out of gas? It could be either your fuel pressure regulator or maybe you have a weak fuel pump.
