My guess is that it could have to do with a number of different things. I notice I need to step on the gas pedal a bit to get mine to start when it's hot out - I doubt my problem is an ignition switch. If you have any more details maybe someone can be of more help. Does it crank over fast or sluggish when it's hot? Bad starter? Fuel injection issue?

Dying to, since you asked so nicely.

Did you check the Temp 2 Sensor, per Cap'n Pike's suggestion, or did you just want to hear that from more people first?

Ignition switch wouldn't seem like the culprit, as it is cranking fine. Or is it? Is it cranking slowly? Or cranking normally just not catching. If cranking normally, then it maybe a fuel delivery issue? Does it require more gas pedal to get it to fire up?

yes, it requires some pumping the gas pedal to get it going.

It takes several attempts and then it starts.

temp sensor, where's that located?

<< it requires some pumping the gas pedal to get it going.>>

You must have have one of the rare carb conversion 89's, where the accelerator pump helps getting that engine started when it's hot & the gas is boiling in that float bowl.

The flexing of your foot on that gas pedal is purely a coincedence at best.

When's the last time a simple tune up was performed on that engine?
Ignition parts all new?
What's the timing set at??

FYI - TK's sarcasm indicator is on full alert. Translated:

Using the gas pedal would be helpful if your van had a carburetor (last offered in the 1970's)
but your 89 is fuel injected & the gas pedal will have no affect on starting.

If it's been a while, you should do a full tuneup on the basics (plugs, wires, dist cap & rotor...even an oil change) before doing anything else.

Do that & get back to us...

Naw--that was kinda a lightweight response.

Trying to figure out what he's got in his description it like finding that needle in the haystack.

What's "Hot"
Needle buried or at normal operating temps?

There obviously isn't any gas boiling in the float bowl, so a basic engine PM would be prudent here.

Besides changing that oil, I'd consider a fuel filter change, check out all of the vacuum cnnections , and initial timing check, besides the tune up.

Then start asking questions of why it's hard starting whens it's hot.

Ya gotta start somewhere-and point A is always the best.

Temp 2 sensor... takes about a minute to test, just slightly longer to replace.

Prior to starting to throw parts at the engine, it would be prudent to perform basic required periodic maintainence first.
Start at square 1, and then look for other possibilities of parts failure.

The OP asked why--without any info of what condition his condition is in.

Why would anyone buy a temp switch from Ricky Recardo, at Go Westy?

The Van-Cafe is a better deal, and much nicer folks to do business with.

I'd bet if he asked Peter what he thought, he would suggest the same starting point--or ask him what he has done to the engine first before going anywhere with buying parts to correct who know's what.
