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

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

1992 Toyota previa fuel pump cutoff switch


This make and model doesn't have a fuel pump cut off switch, the switch is only activated by an impact of 3 G's or more on cars and trucks that do use the switch. Spray starting fluid into the air intake of the engine, if it doesn't start you do not have a fuel pressure problem. Lots of things can keep a car engine from starting, you never mention any tests for fuel pressure or spark or proper valve timing (cam drive belt broken or jumped)

1992 pontiac bonniville dies & wont start , sets a while then starts like normal. doesnt matter cold or hot


When it doesn't start check for fuel pressure, spark and injector pulse. If you got access to a scanner that could read live data check if you get an RPM reference. Check and report your findings.

1985 corvette, 64,000 miles. idles rough and sounds like it wants to die but doesn't; can watch rpm drop and come back. Just changed the egr valve too. What should I try next or look into?


Your problem can have multiple sources. Spark plugs, change those if they are old. Injectors can be dirty. There are injector cleaning products that you can try. The best I have seen is one that you inject the cleaning solution into the system via shrader valve at the fuel rail, disable the fuel pump and run the car only with the cleaning solution that is coming from a pressurized container.
At the same time change your fuel filter. If your distributor rotor cap and spark plug wires are old, replace those. There is an idle control air valve that regulates your idle. That could be a source of the problem also. Query the on board computer and see if you have any codes. My advice, start with the spark plugs, wires, distributor cap and fuel filter if they are old and go from there. That should be an easy task that does not demand a lot of skills. See if that helps.

1985 corvette cranks but won't start, fuel pressure good, oil is good also, it doesn't seem to be geeting any fuel. New fuel pump, filter & gas. Is there a security aystem problem?


Check to see if you have spark, if you do, and still it does not start, then you may think that fuel is not getting to it. At this point, use some starting fluid and spray it at the throttle opening. That should start it for a few seconds and give you the answer.

Took off TPS? to clean up. Replaced with new gasket now motor will turn over but not start. Have spark, no fuel. 1992 vette. Do I need to reset computer? Unplugged IAC and MaF and tried to start. No go....


could have damaged the tps. if the tps shorts out and shows like its full throttle, it goes into clear flood mode and shuts down the injectors. try unplugging the tps and try to start. it it starts, replace the tps.

1992 Corvette won't start




Disconnect the + wire Coils Take #1 Spark Plug Out Get a helper Use Compression Guage if not Available, Just put your finger over the Spark Plug Hole, have help BUMP the Starter over till You can Feel The Compression at your finger you need #1 at TOP DEAD CENTER on its Compression STROKE Fine tune it by using a STRAW in the Plug Hole to feel the PISTON Move UP To VERY TOP Dead center----------------------------------This is Tricky but don't Loose these Instructions------- If you have the OPTI_SPARK Ignition System My Books show all about it but Nothing on the Timing "MARK" as this is the step I Stoped at Above.. Coil Pack Ignition Will Have a Timing MARK On the Lower Harmonic Balancer. Point Being if Mark is NOT on the Degree Indicator It has JUMPED TIMING<< Surly on a Coil Pack Ignition System BUT
-------- The Opti Spark system if there is NO Timing Mark to Go by I Would Suggest Breaking Down and Letting A DEALER Handle it Unless You Can RULE that it HAS JUMPED TIME------------------------------------------------------------------------I Truly Hope I've shed some Light on Your Delima and this Leads you to a Smooth running Chevy. PLEASE don't forget to Rate Me ------------------------------------P.S. The Opti - Spark System Has A BAD REPUTATION Just FYI Recall - Opti-Spark Distribtor, Stall/No Start, Code 16 Notes
