I have a 93 si and last week it started cutting out in low rpms (below 3k). If I steped on the gas and acelarted it wouldent cut out. Now the problem has got worse. Its cutting out all the time, I cant even drive it. I hope its electrical and notinternal . any ideas?

I checked the spark plugs yesterday and they were all burnt looking. I put in some new ngks and now it wont even start. its sounds like its trying to turn over, just not fireing. Still need input, anything (positive) would help.

A few things to check out

-Make sure plug wires are pushed in all the way
-Alternator
-Fuel Filter
-Fuel Pump
-Clean injectors
-Clean EGR valve
-Clean IAC valve

 

ok I tried jump starting it and nothing happened. Its trying so hard to ignite, pissing me off. It kinda back fires too, when i turn it over. Where is the fuel pump and fuel filter located? does this sound internal? Or more like a electiral or fuel problem. If its internal, i beter just buy a new engine. If its not, it could be a good time for upgrades.

Try checking your distributor

 

hey ... just thr
owing ideas at u .. but check ur fuel pressure... and yeh ... check ur destributor..... and yeh... when was the last time you replaced ur fuel filter.... look into that.... because if thats dirty/bad.... ur fuel pump willl go bad....

see if that helps

gud luk

 

not turning over, I would check your distributor first. Then work your way from there..

 

tommorow i will check the fuel filter....wouldent i have to take my distributor somwhere to get it check out. If its electrical or fuel i can figure that out. I will just buy a new ignition and fuel system. The best time to upgrade is when oem **** fails.

 

Since it was running before you changed plugs, I would say you broke a wire or two inside the insulator. If your plugs needed changing, so do the wires, cap and rotor. Have you checked to see if you are getting spark? Go to autozone and get a noid light for a GM. It will fit all fuel injector pgtails. Plug it into one and crank it over. If it flashes that tells you that you are getting signal from the ECU for fuel and ignition which would narrow your problem to the items listed above or an igniter or ICM or fuel system. I would verify fire before fuel.

 

find out whether or not it's getting spark.

 

You guys rock......Thanks for all the input....I hope things work out. I will let you know the results

 

lol don't buy a new engine, it doesn't sound like a serious problem. And even if it is, buy the part, get it replaced.

When you turn it over, does it fire? Check the order of the wires if it sounds like it's gonna catch but it doesn't. I've had this happen with my civic winter beater, I had the wire order in backwards lol.

Also, double check your distributor internals. If the rotor is too badly gone you won't get consistant fire to run the engine. Check for a pop pop pop noise when you turn it over, that's the sound of only a few cylinders catching. Also, check to see if oil is on top of your spark plugs. I've had a CRX die at the track goes a grommet burst and let in so much oil only 2 of the 4 cyl. would fire.
