The plugs are soaked in gas, its flooding itself out is what it is doing. too much gas. when i pull the plugs out they are soaked

I took the fuel line off the filter and cranked it and fuel shoots out. its getting fuel, its just flooding out, i was told the AFM could be the problem if its just broke inside.

How is the air? I ask because a while back a friend had this issue and his darn air filter was about 90% clogged and it did the same thing yours is doing. Had great spark (the "weenie near the fender when I grabbed the plug wire" test confirmed that *ouch*) smelled fuel but wouldn't start. We opened the air box and pulled the filter and when we saw how bad it was we tried it without the filter in the way. I don't recommend driving it like that for obvious reasons but it did fire the first time and run fine. New filter and he was good to go.

Might be an easy fix.

An engine needs 3 things to run: air, fuel, and spark.

It sounds like you have fuel.

Your working on the air problem.

What have you done about the spark yet? You say you have "hot spark", but what does that mean? I would go through your ignition system too...

Let us know what you find out.

I was going to ask if u actually had gas in the gas tank but you answered that already.

Hoping for your sake it was somethng easy.

Can you compression start it? (leave the clutch depressed while going 5mph and in first then rip your foot off the clutch, it should start)

Rustycan

I have gone through the ignition system, everything in it is new besides the coil. distributor and everything, it worked fine til one day it just quit.

Rustycan

Nope it wont it just bogs down.

My 88 truck fails to start floods itself out, i have just discovered a broken blue VSV vacuum, would this cause it not to start??

it is the blue valve on the vacuum system which bolts to the valve cover.


feels like it goes to the back of the fuel rail on one side.

wahts it do? and since its broke is that why my truck floods out?

Wow im stumped...

Rustycan

If anyone has one id buy it off of you, its for a 1988 4x4 obviously. thanks!

got a friend with a toyota? borrow his afm and see if that fixes it..

I guess it's possible your AFM flapper is stuck closed. Mine was stuck open and the engine ran super rich, coughing black smoke. I removed the air outlet hose, the electrical plug, and then just un-snap the 4 clips and it comes right off. I wiped mine out with a rag with some carb cleaner on it. I didn't want to spray anything in there. Make sure the flapper moves freely. 4Crawler has a nice write up on testing it.

Most likely it's your AFM. I have one if you need it.

Rusty - man I have posted all over your threads today. Anyway, there is a vac line that runs to the fuel pressure regulator. I believe more vacuum (at idle or low throttle) should lower the fuel pressure, and less vacuum at wide open throttle should allow higher pressure. I have heard of people bypassing the VSV and going straight to a vacuum tap on the manifold. You could try that and see if it changes anything. I believe I do have an extra one of those off an 89 22re if it turns out to be the problem.

Rustycan

AFM did nothing. FML idk what to do anymore

Rustycan

I fixed the VSV still the flooding issue. i dont know whats next to try. any ideas?

Rustycan

you have a AFM for a 1988? PM me if you want to sell it

InternetRoadkill

I'm not convinced you have an AFM problem. The engine will still try to fire even if the AFM is kaput (that's assuming the AFM isn't stuck in wide open throttle causing massive flooding). The wet spark plugs are saying the computer is working and that it wants to give it fuel.

Did you check for spark? I'm going to guess the igniter on the coil is bad or not connected properly. Also, did you check to see if your ECU is throwing codes?
