Re: Some tune up questions and trouble shooting a running...
Actually.....the 5.0 in the 92 Olds Custom Cruiser is a 307 CI 5.0 L engine believe it or not....The Caprice had a 305 CI 5.0 L engine. There is very little difference, but I have one as well and I found that out through the local dealer. The pulsation you feel when driving sounds like a transmission problem to me, but I think it could be from the timing chain issue. I do not know the timing setting for the car, but maybe this will help you to find it. I would try to make sure which motor you actually have first, the 305 or the 307, and then ask the mechanic at the local dealer what the setting should be.

your question is all over the place--- plugs are dry ? does that mean no fuel --------first is engine turning over --is their spark--is their fuel --i dont understand where you would go from dry plugs to changing out a manifold gasket ---basics first no turn over check battery and connections ---no spark check ignition system ---no fuel check power filters pump
you are on the right track, start with replacing plug wires, then the plugs. first thing i would check. but when you replace one replace them all so you will not have to change a different one every few months. after checking these please let me know what happened, if more trouble shooting is needed i will help you. please let me know if you got covered or if i need to put a little more my brain power to help your horse power.
I am having trouble understanding the question here, What is the problem? The temperature gauge may be bad or the wiring to the guage is why it is not workig if you replaced the sending unit. If it is not runnig good when the engine is cold you might need a complete tune up and this might be causing you starting issues. Have the timiong checked as well.
I recommend giving it a major tune up plugs,wires,distributor cap and rotor and an air filter.I would do this before doing anything else.If it were a problem with the ignition system or the emission system your check engine light would come on.So try a tune up first so that you give yourself a starting point for future trouble shooting.
DO A LITTLE TUNE UP.REPLACE AIR FILTER - FUEL FILTER- CLEAN FUEL INJECTORS BY POURING A BOTTLE OF SEAFOAM IN A FULL TANK OF GAS - REPLACE SPARK PLUGS AND WIRES.IF ALL IS GOOD SOUND LIKE FUEL PUMP FUEL PRESSURE SHOULD BE 41 - 47 PSI. REASON I SAY DO A TUNE UP.IF EVERY THING IS WORKING PROPERLY. THAT WAY YOU WONT BUY A NEW PUMP FIRST AND SPEND EXTRA MONEY.ALL YOU NEED IS A TUNE UP WHICH WOULD BE CHEAPER ON FIRST CHOICE. WHEN I TROUBLE SHOOT I ALWAYS TUNE ENGINE UP FIRST THEN I CAN GO TO NEXT LEVEL.I TROUBLE SHOOT IN STAGES THEN I FIND PROBLEM QUICKER.
There is a trouble code set in the pcm( power control module). To be able to get the code and understand what is going on you need to take the car to a parts place like auto zone to have the pcm scaned for that code. They will scan it free and then you will know what the pcm is trying to tell you. Hope this will help.
Don't understand your question. Do you mean CHECK ENGINE LIGHT? If so, then there's one or more DTC's (Diagnostic Trouble Code) stored in the ECU (Engine Contro Unit). You'll need an OBDII (OBD = Onboard Diagnostics) scanner to retrieve any trouble codes. Find one (can be purchased at AutoZone, CarQuest, PEP Boys, O'Riley's, etc.) Let me know what codes are stored/set in the ECU. If you don't wish to do this, then take the veh to a Hyundai Service Center and pay their diagnostic fee. They'll give you an estimate of repairs (parts, labor, tax, time-frame, etc.). This way you'll know EXACTLY what the problem is and what's required to fix it.
