EZGO gas golf cart won't crank. Engine will turn over but won't fire up and run. Sometimes when running engine will just quit running. Three trips to one dealer and he can't find anything wrong. Three trips to another dealer and it quit running or wouldn't start and he replaced carb., fuel pump, ignitor and air filter. Second day home and it ran good for 1/2 day and now won't crank. Does anyone have any suggestions to fix it? I need HELP! Larry

Has it been checked for:

1. Bad gas (fuel)?

2. Contaminated fuel?

3. Clogged or debris in the fuel line?

4. Clogged fuel filter?

Water in the fuel will also cause these issues.

I'm not sure what an "ignitor" is-spark plug? But, most all the small gas engines use a magneto for spark, there may be some electronics involved somehow now. I'd look there along with wiring.

Magnetos generally run forever, which is why any problem might be over looked. Plus, getting to it involves real work (pull the flywheel). When you have no start, pull the plug wire, attach a working plug, ground it and crank. You should see spark at the gap.

Earlier this year I discovered our UTV wasn't 4x4 no more. Solving that involved electronics and in the process I discovered that the wiring harness has 5 diodes buried in it (and no, the factory service manual doesn't tell you where they are, but the trouble shooting instructions were great) to take care of various things. I hate it when engineers just have to "demonstrate their grasp of available technology". [Quote from the excuse of an engineer for the unbelievably overly complex and completely unsuited for the purpose tool they designed.]

I used to have to escort electronic techs. They hated intermittent issues, they generally just did a cursory inspection and waited until the glitchy part smoked to solve it.

Gas engines require fuel, air, ignition and compression. One of those is the culprit. Air is seldom the issue. If it's getting fuel and has spark, do a compression check. You may have s sticky valve or adjustment issue.
 
It's either electrical, mechanical or fuel.


Sorry that's all I got which is nothing!:)


Sounds like the night mares I had with a outboard engine. Stator was going bad


Is it a 4 stroke or 2 cycle? (never mind)


"When we created a first-of-its-kind, purpose-built gas engine for golf cars, we knew we had to deliver performance no one else could match. So no detail of EX1's design was too small to examine and refine.

  • The EX1 electric fuel injection (EFI) system not only optimizes your miles-per-gallon but also produces the lowest emissions of any golf car on the market.
  • Smart Engine Management monitors the electrical system, shutting off accessories when they're not in use, helping to make EX1 the industry's most efficient engine.
  • An integrated starter/generator lets EX1 work like a hybrid engine, auto starting and stopping as needed for fuel economy.


  • Fewer wear parts and two-year oil change intervals mean you spend less time and money maintaining EX1.
  • With its smaller, faster-spinning 150cc design, EX1 is the pinnacle of quiet efficiency. Competitors rely on oversized, generic industrial engines which generate the thump usually associated with gas golf carts.
  • Thanks to EX1's starting clutch, you'll hear none of the downhill belt whine you experience in other cars."
 
Im working on what hasn't been mentioned.
when it is running, it is assumed it performs this mission well ...until it doesn't.
If so, it lacks the tell tale signs of fuel/ fuel delivery issues. Being poor performance, sputtering and the like.
When it does start, it is assumed that it does this with relative ease. If so, it has compression and most everything is right in it's universe.
a sticking valve could do the same I suppose but I suspect it'd sputter and argue while its sticking.
Coil ... yeah, that can do it with heat, though it sounds like the issue manifests from a cold start as well.
Coil and wiring ....

Doesn't crank?
All the air, fuel, spark is going to help if so.
Check the battery.
If the battery is good, I'd try jumping from the battery to the starter and see if it cranks.
Yes?
Check the starter solenoid switch and ignition switch.
No?
Sounds like a bum starter.
These only apply if it doesn't crank.

Which is it? "Cranking" and "turn over" is the same thing.

Possibility of a loose or broken wire causing it to die out.
I have seen wires that were broken inside the plastic cover and only showed up when you tested the wire with an ohm meter.
 
That has all the hallmark of an intermittent ground for me. Many years ago in the UK I had a car that developed a fault in the ground line from the battery. I could swing all my weight on the cable, but it didn't pass electrons properly. More recently I had a ground come loose on the motor of a 3.2 Isuzu Rodeo. Symptoms were weird and the vehicle would run but the alternator light would come on and the A/C would quit running.

The strangest one was a car that just quit running on a main road in England. After much head scratching, I realized the coil had rotated in its mount and one of the terminals was contacting the block.
 
While we're telling stories,...
I had an old Harley that would pop and misfire every time I accelerated up a steep hill near my house, no other time. After years trying to diagnose this intermittent problem, while looking for something else on the bike I noticed an irregularity in a wire running past the solo seat post.
It turned out being a wire running over a grease fitting that got pinched and momentarily shorting out. Every time I accelerated up the hill, the seat spring compressed more than normal, pushing me down in the seat and pinching the wire, causing a short.
"If you can't fix it with a hammer, you have an electrical problem."
 
You need fuel, air and ignition. Check all your cables for tightness, esp. your ground wires. It's probably a loose cable which causes a disconnect with vibration.

My guess.

Hope it helps.

^^^^^^THIS.

Does the starter turn the motor over, regardless whether it runs.
It's 2 different things.
