My 1992 Chevy corvette lt1 is not starting is getting fuel to the jet by the intake what do i do?

This vehicle should be fuel injected and therefore have no jets. If you are referring to a schrader valve on the fuel rail having fuel then maybe I can offer some help.You need to pull a spark plug wire off and see if there is any spark from the wire if you are sure there is fuel supply.Check for spark and let me know

Why doesnt my 1992 corvette start and has no spark or fuel?

Coil? Coil wire connected? Fusing. or the opti was installed incorrectly. Did it run prior to repair?

Gas shoots out from muffler and car runs like it miss just started all of a sudden on a 1988 corvette

Check spark plug wires and spark at each cylinder.

One can check with an inductive timing light on each spark plug wire to see if spark is available at each cylinder.

My 1992 corvette will not idle above .5 rpm wants to die.

Sounds to me you should do some checking and diagnosis first. Start with simple stuff like checking the spark plugs to see if they are fouled or if you have a damaged plug wire or even a loose or unhooked plug wire or plug. Then check all your vacuum hoses to see if there are any that are damaged, dry rotted or not functioning. Then check O2 sensors, idle control valves etc...

Finally if you've checked all that, then I'd opt for a new optispark (the term used for the distributor on these engines), and that's quite a labor intensive job.... and a new optispark is rather expensive at around 300-500 US dollars.

Good luck.

I am replacing the the spark plugs and wires on my 92 corvette lt1 engine, but to change the wires seems impossible because they are under pulleys. any suggestions on how i should do it??? should i remove...

You don't have to pull the fenders off. The passenger side is fairly easy. On the Drivers side it is more of a challenge. First, remove the serpentine belt. Then remove the belt tensioner which is held on with one bolt. From here you can get to the wires on the drivers side of the opti spark. On the plug end you may need to remove a couple of bolts or the ASR mounts but if you work at it, you can fish them through. Don't do them one at a time under the Alternator. Put them in the clip and run them to the Opti-Spark. It is not fun but with patience you can get the plug end take care of without busting too many knuckles.

It sounds as if the Ignition Control Module has failed. Remove the easiest spark plug you can reach. Reattach the plug wire and clamp the plug down to the valve cover or something that will make a good ground or electrical path. Have someone crank the engine while you watch to see if there is a spark across the electrodes. DON'T HOLD THE PLUG WHILE YOU DO THIS, IT WILL KNOCK YOU ON YOUR ****! If there is no spark chances are the ICM is bad. It's located on the left front behind the Pwr Steer Resevoir on the engine block. You might be able to remove it, 2 small screws, and have it checked out a a parts store. If you don't have any luck with this post your problem on There are many there that will help.
