no fuel to injectors help!

[drifter134]

hey guys

wonderin if u could help me i own a 1991 surf LN130 chassis with the 2L TE motor it all started when i decided to run it on veg oil and i think it has gone very wrong

i was driving around 1 nite and the proformance was very bad so i decided to put some diesel in and it helped for a bit till i was driving down the road and it just stopped dident splutter or anything just stopped like its an electrical problem the next day i drained the tank put fresh fuel in and replaced filter bled system up and went to start it and it dident go so i cracked the injectors open and cranked it and no fuel came out so then i cracked the pipes on the back of the pump but no fuel came out could this be the solinoid playing up and if so where is it and where does it get its feed of power from many thanks lewis

they're normally fine on veg oil, other than the pump seals leaking sometimes, but i don't think that would cause it to cut out or not start.

was it new or recycled veg you used?

They don't have a solenoid. It's a Spill Control Valve. Do not connect to battery voltage. It's powered by the ECU at around 5V. Top rear of pump is where it is.

It may or may not be relavent, but what % veg oil were you running, 60% or less will not cause any problems apart from lifting any muck from the tank, but that should get caught by the filter.

Any updates on this?

Same thing has just happened to me.
Was driving along when the engine just lost power and rolled to a stop, no spluttering, with the symptoms of running out of fuel.

As veg oil lifts muck I am presuming it is the filter which I am going to change as soon as I get some available time during daylight.

If your getting no fuel out of the pump it can be the spill control valve like Nev said, but also check the fuel temperature sender that is in the side of the distributive head of the pump, there is a small gauze filter under it when you unscrew it, it could be blocked.

What sender? Do some pumps have something I don't know about? As far as I know there is only a plug and o-ring. I even have a new pump here and it's the same.

ok found a temperature sensor but it's on a 1KZ-TE pump and not on the 2L-TE.

Sorted! I thought EFI 2.4's had the same sensor, but didn't have one here to look at, do 2.4 pumps have the filter still?

[NiftyNev]

do 2.4 pumps have the filter still?

None according to the EPC diagram.

engine died....

Just to conclude this thread... (on my part at least)

Changed the fuel filter, primed the system and after a few cranks of the engine she fred up.

The old filter was full of a jelly like substance, presumably the diesel varnish .

its taken me a while to get round to looking at my surf but i think i may have found the problem like i said my surf stopped dead no spluttering or nothing i checked the feed to this spill control valve or what ever u wanna call it i thought it was a stop solinoid but anyways.....there are 2 wires goin to it this is located on the back of the pump to the right hand side as if u were looking at the pump checked this with my multimeter when i switched the ignition on there is no power going to the wires so i removed my ecu my friend has the same surf and i pluged my ecu into his tryed to start it and nothing checked the feed to the wires and no voltage as before with his ecu in the voltage on the wires read battery voltage but i dident want to put his ecu on my surf just incase i have a faulty component or something
has any1 come across this before ?? is it a common problem for a surf to burn out an ecu after running veg oil ?? what do you people out there think do i risk plugging another ecu into my surf??

[kkingfishers]

hi

have you tryed taking the fuel cap of then take the pipe of the filter and blow down the pipe ive just had the same prob if was the pipe blocked good luck

Veg oil won't damamge a ECU, its just a mini PC getting and sending inputs to and from the motor.

I've had 2 surfs in the garage over the years that the ECU Spill control circuit has failed, its just life. You need a new ECU or that one repaired.

cheers mate at least u have shed some light on it i was begging to wonder that i had a major wiring problem or running veg oil had put stress on the pump and done something cheers
