Not starting after sitting all winter

Good morning,

Does the theft or security light go out after about 10 seconds with the key on?

This sounds like the security system is shutting it down. I attached a guide below for you to try to see if it gets it out of the security lock.

The key is not chipped.

Okay, if you spray some starter fluid in the air filter, does it start and stall?

I would also check the compression to be sure the timing chain is good. You need 140-160 pounds.

140 170
170 195
140 165
190 170

Okay, that is good.

What about spraying the starter fluid in the air filter? Did it start and stall?

Roy

When i squirted fuel into throttle plate i had to step on accelerator as if it was flooded. It did not start with extra fuel being squirted into the throttle plate.

Did you verify the spark by removing one of the wires and checking?

Roy

yes had a wire connected to plug from coil and grounded plug.

After you shut the engine off, does the fuel pressure bleed down? Looking to see if you may have an injector leaking.

Roy

about the coil no misfire codes. It may leak down 2-3 PSI.

Okay, I would remove the valve covers and make sure all the valves are moving.

We had a big storm so after i finished pushing snow with the loader i started back onto the truck. Tried to start it with WOT twice and it started. Try ing to figure it out. Runs the same as before. No codes. Thanks for your time.

Did you check the actual fuel pressure?

Roy

Yes 59 PSI. I also bought another fuel pump gauge to check. They both had the same PSI.

Then the next step is to check fuel quality. From sitting a long time, the fuel itself may be the issue.

Roy

Checked that. quality is good, no water, clean. put fuel in a open container and it burns.

Okay, circling back to spark, you may have a weak spark. Did you verify battery voltage to all the coils?



Roy

No, i did not.

I would verify this and get back to me with the results.

Roy

okay.
