2000 Will not start without engine warmer

[tntmarler]

Ok, here's the deal. When I got this truck it was blazing hot in August here in Louisiana and the truck had no starting issue's. When it started cooling off the truck would turn over for ever and never catch, billowing out white smoke. Had the glow plugs replaced, didn't help. The one thing that I was wondering about is that I have to pull the gear shifter up because it has gotten loose and it engages the neutral safety switch. I was wondering if while it is engaged if it would prevent the glow plugs from cycling properly.

Did you replace either of the glow plug relays?

Mine used to be hard to start under 40 degrees, and wouldn't start under 30 without being plugged in.

Replaced the glow plug relays and havent plugged it in since.

Might have to give that a try, but it can be over 80 degrees and when it does fire up it's a hard start with almost no power until it gets good and hot. Sound like anything you've seen?

Nope. Sorry

[tntmarler]

You said relay's? How many does it have? I only saw one.

[ToddOH43]

I was under the impression that there are two.

Well there is a intake heater relay that is right next to the glow plug relay. Ironically, they are the same relay.

Well see...if you pay attention you can learn something every day.

So far I've learned two things in this thread

1. There is only 1 glow plug relay
2. Some people consider 80 degrees a cold start

Only 1 relay.

Go to napa and buy a gp109. They list a gp110 for our truck but it is more money and the only difference is, it is turned 90°.

Might want to check the voltage out of the relay and see what your getting before a replacement.

Will do, do you know if Auto Zone will do the test? I don't have a volt meter.
