    Hello everyone.

    I’ve been dealing with a no start issue on a GSX I purchased a little over a year ago. Back story is the car had sat for four years. Guy said it was leaking antifreeze but he wasn’t much of a mechanic so I took it off his hands.

    Take it to my place, drain the fuel and put new in. Starts up bad has a bad miss, and the head gasket was leaking. So I tear the head off, turns out two exhaust valves were bent as well. For the age I decide to buy GSC Titanium Valves and put them in, lap them, etc. Put the head back on all together and fires up for the first time. Runs for three minutes like a champ and starts to hiccup like it’s running out of gas so I shut it off, put new gas in. Try again. No start.

    Check fuel pump ends up being the plug burnt on one end. Replaced the plug and put a new fuel pump in and started but backfired. Checked timing multiple times it’s okay. Replaced fuel filter and injectors. Now car just acts like it wants to start but doesn’t. Checked compression, it’s equal all the way across. Have fuel to the rail, have checked timing multiple times and it’s on point.

    What to check next?? I feel like it’s a sensor or something, I have a CEL but it’s for the rear o2 sensor and it ran great in the beginning without it. Have open down pipe and aftermarket exhaust manifold that is it.

    Open to any suggestions I want to get this car back on the road like it deserves. Refreshed the whole suspension and everything and it’s sat on jack stands the whole time I’ve owned it.
    Thanks.

    I’ve read that thread thoroughly, with no luck. I have spark, fuel and compression. And my timing is correct. Hence why I’m here asking for help.

    Fuel at the rail but are the injectors firing pull them off, get test light and see if you have any voltage to them. Spark at the plugs? Is your coolant temp sensor bad?

    Have spark at the plugs, I believe the fuel injectors have voltage but I’ll double check that. No idea if coolant sensor is bad, I was reading about testing it in hot water so I’m probably headed to that point.

    What is your fuel pressure? Having fuel at the rail doesn't mean the system is holding good pressure.

    A way to check cels would show a cts sensor failure.

    Could potentially be a faulty fuel pressure regulator or coolant temp sensor

    I have voltage to every injector, with the key on and when turning the motor over. I don’t have a code for the temp sensor, possibility it’s bad without throwing a code?

    Other signs of a fpr being bad other than fuel running out the vacuum line? Next on the list is checking fuel pressure. Going to run to the mechanic shop and borrow the tool to test it.

    You need to check for injector pulse asap, borrow a noid light set from your local parts store or you can use a test light if you can have someone crank it while your under the hood, are your spark plug wires in the right order? are your spark plugs new?

    Plugs are new, plug wires are in the right order. Tested every injector plug and each jumped from 2 ohms to 4 when cranking engine over. Replaced power transistor a while back, don’t believe my old one was bad since no change.

    You cant ohm check the injector or harness when cranking it over, you will not only ruin your meter but it tells you zero about anything, you need a noid light set or a 12v test light to do it right, you could even have clogged injectors or fuel filter from junk stirred up in the tank.

    Have you checked the wiring at the back of the coil pack. Make sure they are in the right order.
