Intermittent problem? feels like it jumped time

My truck has had an intermittent problem for a while. To start I changed out a bad battery a few months ago. A couple of months later I was hauling a load on a hot day, and it started spitting and sputtering. It turned out to be the fuel pump (mechanic did pressure test). These things might not be related, but..... Two weeks later it sputtered and died on the way out my driveway. It would not start, so I had it hauled to the shop. My mechanic changed the distributor, and said the next thing was computer. A few days later it was acting up, and I took it to him to find out where the computer was. I asked him if it might be the ignition module, and he took it for testing. They said it is fine. It went dead again, so salvage computer. Now it has died again, and when I try to start it it seems like the timing is off. I have had trouble that felt like timing throughout the whole thing but it is intermittent. Change the module, or something else?

Check the crank sensor and the drank balancer pulley for wear in the keyway...Not a guaranteed fix, but somewhere else to look.

Why do I have an intermittent problem with ABS and power steering lights?

Bad or loose intermittent wire connections to and from sensors. Some unauthorised mechanic has been working on the car? Take it back and talk to the service manager, or the shop owner.

2004 nissan frontier intermittent starting problem with shift lock

Shift lock is just a safety feature, so you have your foot on the brake, when you put it in gear. It has nothing to do with starting the car. Intermittent starting problems can be a few different things. Ignition switch, park/neutral safety switch, wiring, and corrosion. If it clicks when trying to start, it cold be loose/corroded battery cables or a bad battery.

Intermittent starting

the starter selenoid is most like bad or you could have a short in the wire to your starter causing heat to build. Heat causes battery to not be able to turn the cars engine. waiting lets the resistance to disapear. and the cycle continues

Am having starting issues on a 2004 GMC Canyon, alternator or engine switch?

Hi beagleclub,

Could be the battery or cables too. Could you describe the symptoms in greater detail?

Does it start with a jump?
Do you just get a series of clicks?
Do you get no response?
All the time or intermittent?

Any other info you feel is pertinent will be helpful
