Go to a library that has a set of the factory service manuals (not Chlton's or Haynes or Motor's). The FSM's will give you all the trouble hotting charts that the dealer techs use.

97 honda civic wont start,got fuel,spark,compresion,new timing belt,its in time,new spark plugs,new distributor cap,new crankshaft position scensor


I would suggest to get a propane torch and turn on with out lighting it (flame less) Place in intake port to manifold crank and see if starts. this will let you know if injectors are cycling or not. This engine has Three sensors that keep the engine running crank,TDC,cam. The TDC and CAM are in the distributor and crank is behind timing belt cover.

My 1997 gmc 1500 suburban will not run but it pulls no dtc codes on the cpu


My 97 Suburban had a similar problem. Would not crank on a regular basis. Replaced spark plug wires, plugs and rotor cap. Vehicle cranked and ran just fine, plugs were in poor shape. Checked fuel pressure, above 55psi with engine running or just the switch turned on. Immediately after switching engine off the pressure would bleed off to "0" PSI. Otherwise everything OK. Problem solved, so I thought. A couple days latter I had to make a road trip from Mobile, Al to Fort Meyers, Fl when cranking problem re-occurred after approx. 100 miles into trip. I stopped at parts houses on the way to ask questions and to obtain their best ideas, at times it would take 30 minutes before engine would again crank after making a stop. I replaced almost all of the sensors. Finally made it to Fort Meyers that night. Next morning vehicle was dead would not crank no matter what I tried. Fuel pressure OK. Only thing left to replace, Fuel Injector spider system. Problem solved.

97 gmc 2500 5.7l vortec, won't start, fuel pump works, tried using starting aid and nothing, hooked up a scan tool, and no errors came up, could it be the crank position sensor? or the distribution centre...


See if you have spark on at least two plug wires. If you do, but it is weak, you may just need a good tune up (plugs, wires, distributor cap, and distributor rotor). If you don't have spark or it is only on one wire, take the distributor cap off and see if the distributor is turning while someone turns the key. If it doesn't spin, you need a distributor because the bottom gear is broken or stripped. If it does spin, then it could be the coil, ignition module, crank sensor, fuse or wiring to any of these parts. It will take a lot of wire testing and diagnostics to figure out which part it is if it isn't just a simple tune up or distributor.
Hope this helps. Good luck!

My 2000 jimmy stop running. i have fuel presure, spark plug wires have spark. I replace both crank, cam, ignition modual sensor and the ecu. Also took of the mufler tinking it may be plug. Engine turns...


yeah, check the order of the spark plug wires on the distributor cap. Perhaps they might be mixed up not allowing it to run properly and yes, even sometimes stall. check that first if not, then check to see if you are getting fuel at the engine. If not then perhaps its a bad fuel pump...good luck!

I have a 1997 Gmc Sierra 5.7 4x4. It has no spark. I replaced the coil and ign module today but still no spark. Tech suggested Crank shaft sensor? Truck was running then died going down road. (30kms after...


It could be the CPS, but as you now know throwing parts at a repair is costly and sometimes it does not fix anything. A code scanner should be able to tell you if the sensor is bad. If the CPS goes bad you will have no spark.

1997 gmc savana 4.3, wont start ,has new fuel pump, new pressure regulator, new spark plugs , i cleand up the maxi ijector, looks ok no leaks,i do have spark and fuel but still wont work any ideas


only 3 things will cause this engine not to start (crank and not start) fuel, ignition, timing.
You haven't mentioned the engine cranks over or not, so I have to assume it cranks over.
Possible timing chain or the crank sensor on the timing chain. Have you checked this? you need to remove number 1 spark plug & when the piston is in the full top position on compression, remove the dist cap & see what spark plug wire the rotor is pointing to inside the dist cap. (I'm sure if you google checking for top dead center you'll find the proper procedure)
