No we did not get it started again. We ended up getting towed home and now i'm trying to figure out what happen. I thought it would be some short because of the cruise control, but all fuses are still good. I've changed the plugs, wires, coil, and igniter but there is still no spark.

Wheres the pics? I've always wanted to bag one of these things to the ground...

no spark....hows the distributor? Bad grounds? How do you know its got no spark? Something else? Fuel prob? Is there oil pressure?

Well my dad's friend which is some what of a mechanic did some spark test and a fuel pressure test. He is unable to work on the RV during the week. So the old man asked me to take a wack at it. He told us that there was good fuel pressure and no spark.

Today I just went over and checked the pick up coils with the multimeter and they all passed. I'm working on the tap test now and trying to find a second test light in my garage.

Since I'm just rechecking my mechanics work again. How would I check for spark or fuel pressure?

Thanks,

I just pulled a spark plug and held it up to the grounded metal and no dice.

another update!

Well I went through the entire "No start condition" thread some one had posted and I believe I narrowed it down to the igniter, which I have replaced with a junk yard igniter.

This is my results:

Terminal-1 White NE signal = 200
Terminal-2 Red G1 signal = 150
Terminal-3 Black G2 signal = 150

All 3 Pick-up coils passed the test.

Blue/Black wire on igniter harness = no spark (- or +)

+ battery voltage on coil = good

Second tap-test test-light on negative coil = no flash

Black/Red wire at the igniter voltage = good

All other wires look intact and there seems to be no grounding issues. On the RV we have a mounting bracket that holds the cruise control unit. I'm wondering if correlation with the cruise control and the igniter.

That's one of the cleanest engine bays I've ever seen posted on here!

Thank you! There are a few on craigslist if you want to join the toyota motor home club

Thank you... I'll try to get a shots of the entire engine bay.

I just ordered a igniter from ebay. Same part-number and all with a 30 day warranty. Hopefully this one fixes my spark problem.

Thanks for all the help!

update:

We finally figured it out! We unhooked the maf to see if it would run and it did! Opened up the maf cover and saw some loose soldering. Just soldered it back on and everything is running fine.



Thanks for all your help.
