Ignition control module? Bad grounds? Fuel pump relay? Bad compression? Timing chain or belt? Better start troubleshooting and stop throwing parts at it. This could get expensive in a hurry.

Take spark plug out and rest on top of engine. Needs to earthed. Crank engine and check for spark. Next check for fuel. Disconnect injector and check for squire of fuel, catch in a container. Not good to have fuel down side of engine. If not fuel could be fuel regulator or pump, another sensor here. Last thing timing, but unlikely unless you had reason to take timing chain off. Now give up and see mobile mechanic to plug computer on clear all faults and then try again. Good luck

SOURCE: adjust timing on 1998 GMC K2500 pick up 5.7 liter

It has to be done with a scanner. You can adjust this distributor, but there are no timing marks to watch as you move it. There is a timing mark on the balancer and on the timing cover for referencing Top Dead Center #1 cylinder only, but it is only used for dropping the distributor in to get the engine up and running. A scanner is needed to properly adjust the timing. Connect the scanner and look for a data parameter labeled ‘cam offset’ or possibly ‘cam ******.’ It will be listed in degrees. Start the engine, and bring it up to 1500 rpm. Note the reading. If the timing specification is not within plus or minus two degrees of zero, you need to move the distributor. You can move the distributor with the engine running but the timing will not change. After you move the distributor, the ignition has to be cycled off to let the computer learn the new timing spec. Restart the engine, bring it up to 1500 rpm and see what the new spec is. You must repeat this procedure until you get the timing into the specification as mentioned above. Once you have it set to spec, the code should clear.

This could be a number of things but i think that your problem sounds like a vacuum leak or an EGR problem. Try listening for leaks and try un-plugging the EGR solenoid valve one time.

SOURCE: GMC JIMMY NO START BUT GOT SPARK AND FUEL

try the oil pressure switch, that was a common problem on Gm trucks when I used to work on them, the oils switch was bad and woulden't allow it to start and the ones I worked on were on the back of the distributor.

Engine swings but does not start


Your testing so far seems to exonerate components #1 to #5, and #13.
Since you've already replaced a number of parts to address the problem, I thought I should try to be comprehensive:

Priority Action Part Type Cause
1 Inspect Ignition Switch - Improperly Connected or Faulty Ignition Switch.
2 Inspect Battery - Battery Discharged or Faulty.
3 Inspect Battery Cable - Coroded, Broken, Shorted or Poorly Connected Battery Cable.
4 Inspect Starter Solenoid - Starter Solenoid Faulty.
5 Inspect Starter Motor - Starter Motor Faulty.
6 Inspect Wireset - Worn or Damaged Spark Plug Wires.
7 Inspect Ignition Coil - Faulty Ignition Coil.
8 Inspect Distributor Cap - Loose, Cracked or Worn Distributor Cap.
9 Inspect Spark Plug - Incorrectly Gapped or Fouled Spark Plug(s).
10 Inspect Distributor Cap and Rotor Kit - Loose, Cracked or Worn Distributor Cap, or burned rotor contacts.
11 Inspect Fuel Tank - Fuel Tank Empty.
12 Inspect Carburetor - Worn, Faulty or Damaged Carburetor.
13 Inspect Fuel Pump - Faulty Fuel Pump.
14 Inspect Fuel Pump Strainer - Fuel Pump Strainer Clogged.
15 Inspect Fuel Filter - Fuel Filter Clogged.
16 Inspect Air Filter - Air Filter Clogged.
17 Inspect Fuel Injectors - Fuel Injectors Clogged/Inoperative
18 Inspect/Test PCM - Powertrain Control Module (Computer) defective - sending incorrect ignition/timing signals to fuel injectors
19 Inspect Fuel Rail - Fuel Rail leaking/broken causing inadequate/low fuel pressure.

Use a HEI (High Energy Ignition) tester to see if you have spark to your sprak plugs - if not, suspect Ignition Coil, Distributor Cap, or Distributor Rotor.

I just replaced the battery. Car cranks but does not start. I dont think its the starter. what can it be?


Lotta things - first things to check are tune-up items: spark plugs, spark plug wires, air filter,
rebreather filter, oil filter, fuel filter, in-tank fuel strainer, ignition control module/distributor cap/rotor,
PCV valve

Most probable cause: lack of spark from the ignition system
2nd most probable cause: engine starved for fuel due to fuel system problem: fuel filter, fuel pump,
in-tank fuel pump or clogged in-tank fuel strainer.

1998 GMC Sierra 2500 5.7L hard cold starts last month, now won't start cold w/o a little carb cleaner in intake. Codes for oxy sensors, mass air sensor and crank/cam position. Drove today, no power just...


starting definately has a lot to do with the crank/cam position sensors, but it wouldnt have nothing to do with hot or cold weather, oxygen sensor will make the vehicle run too rich if its out, you will smell fuel very strong out the exhaust, that could make it run sluggish also, and usually if the mass air flow sensor goes out the vehicle wont start at all...

Ford focus 1999 2.0 ltr,engine turns but doesnt always start


If you hear that the engine cranks when you try to start the car then that is good. It means that the starter is working. If the starter cranks but the engine won't start, there could be wide range of problems. Here are some of the most common:
- Problems with fuel delivery system (e.g bad fuel pump, fuel pump relay, clogged fuel screen, etc.)
- Problem with engine electronics (e.g crank sensor, cam sensor, air flow sensor, power relay, engine computer, etc.)
- Ignition system problems, especially on older vehicles with the distributor (e.g bad ignition coil, commutator, rotor, distributor cap, etc.)
- Defective ignition switch
- Problems with vehicle security system
- Internal engine problems (e.g broken timing belt or gear, low compression, etc.)

It has a problem starting i want know what could be the cause or causes of this?


Is it crank no start? no crank ?, slow starter? clicking noise at the starter?
Check battery and cables on battery and off of starter. Check starter relay and ignition switch.
Now if it cranks and doesn't start, check coil, wires ,plugs (distributor,cap, rotor if applicable).
Then go to fuel checks . The only fuel check I recommend that you do is to put the key inthe ignition and turn it to on position ( you should hear the pump buzz) if not you may have found your problem.More detail fuel checks should be done by a Certified Technician for the obvious reasons.

WON'T START ENGINE JUST TURN OVER JUST CHANGE SPARK PLUG ROTOR DISTRIBUTOR CAP / SPARK WIRES


My first guss would be a fuel pump, just would have to verify that when you first turn on the ignition to crank you can either hear the fuel pump turn on in the tank or not, if you cannot hear the buzz or whine noise from the pump in the tank you need a fuel pump. Fuel pumps are a very common problem with these trucks.
