4age Died - Fuel Blockage? HELP! Tue, 28 June 2005 00:32 Go to next message
Hi all,

My sprinter died last night, had to have it towed from the calder fwy.

Sunday Everything was fine...car running well. Sunday night I went for a drive and car was extremely slow, I blamed a fat arsed mate who was in the car.

Monday morning, still slow, idling lower than usual but drivable - went to work.

Monday afternoon started car to drive home from work, was extremely crap, but assumed problem would get a little better when it warmed up. Made reasonable power above 4000rpm (if it got there).

Could barely get to 90kph on western ring road, had to slow for some other bogans broken down car, couldn't get above 60kph.

Eventually stopped on the exit to calder fwy, where I stopped and noticed smoke emerging from the bonnet. Having a look the exhaust manifold was glowing red.

I am running a sv21 camry swimmer pump in the standard sprinter tank, no breather. new efi filter. This setup has run well for a few months. The fuel pump is definately running - whether it is actually pumping anything, or whether there is a block in the lines somewhere I'm not sure.

Any ideas?

Cheers

Clayton

start pulling bits out and checking..

first thing to do would be to measure teh fuel pressure in the fuel rail... if that is ok, then you need to look elsewhere, but if it's low then the prob is between the pressure reg/ rail/ lines/ and pump/tank.
basically it's a process of elimination

thanks, just getting some opinions and suggestions as I can't look at the car until the weekend.

Any problem not having a breather line on the fuel tank? it sucks a bit of air in when you remove the fuel cap. Is it possible that it could vavuum the tank so much that it couldn't draw petrol? (No i haven't opened the tank and tried starting it again yet).

Cheers

I can't be sure whether it is a fuel problem or not, it's just that it progressively got worse.

I doubt it's a banana, unless you put one there?

I can hear the injectors ticking, I can get the car to idle - jut not rev, unless I kink the map sensor hose, then I can get it to rev up a little.

that was my manifold... was red but photo came out funny.

Try squeezing the fuel return line with a pair of pliers to block it off.
This will increase the fuel pressure in the rail. See if it revs easier with the line blocked.

Have you had the injectors cleaned and flow tested.

I would also check the timing.

Don't know if any of this is relevant, but my 4agze made hardly any power below 4000rpm, ran rough as guts when cold started, misfired a fair bit on idle, and after a short drive the extractors were glowing hot...

Turn out the exhaust cam was a tooth off..

Now you problems sound more involved than this, but it's something you can check and cross off the list.

all good ideas! thanks for the help.

I doubt it's anything timing related (whether that be ignition or cam) as the car was running fine, drove it a few hours later and it was stuffed... and I didn't see anyone under my bonnet in the mean time.

Cheers.

if you have a dizzy (dunno if its the same with the crank angle sensors) on mine one of the bolts holding the dizzy came out and one loosened making the timing advance and retard itself.

needless to say i fixed it right away..

you might wanna get a timing light to check your base timing it cant hurt..

it sounds like it could well be a timing issue

Had the same with my 4AGE a few years ago.......dirty fuel blocked the fuel filter after about 1 hour of driving.

Same symptoms as you describe.

Stop the car, leave it for 30 minutes, start it up and it goes for about 15 minutes before dying again.

Cleaned out the injector baskets (off-car injector service) later to ensure no muck had got through to there as well.

I had recently filled up from a bp in preston i haven't ever used before. Probably coincedental, I'm sure that 20 years of crap from the sprinter tank got stirred up during the conversion.

that one on st georges rd? i use it all the time.

changing filter wouldnt hurt, its only 10 bucks or so, just do as many cheap things as you can at the same time, so you dont know what was causing the problem.

Changed fuel filter - seemed harder to blow through than the new one... but the new one was completely dry.

Engine was worse again than the last time i tried to start it... at least before it idled, this morning it fired a little.

Changed fuel filter, no firing at all... turns over fine.

What in the hell deteriorates like this? I am waiting for my mobile mechanic to bring around a spark plug socket so I can begin targetting the problem. The dizzy is bolted down tight, and hasn't moved.

doing my head in!

ok, main pully was loose... (explains the clonking noies i was scared to investigate).

With pully on 0deg (to the timing mark on the pully) should the dots on the cams line up with the lines on the backing plate? they are both off by about a tooth.

I'll search that now.

New pulley installed! still wont start...

if I try starting it for 20-30 seconds it almost starts (fires, gains momoentum, overtakes starter motor, let off key and it dies)

Turning the engine around with ignition on i can hear injectors firing.

Can anyone think of the effects of driving around with the cam timing way out? Like could it have done something funny to the plugs? I don't have a plug socket here so I can't really check just now.

for you headers to get red hot it could be an exhaust blockage, check your cat, heard many stories of them fucking out and causing loss of power and general fucked motor response.

thanks jxt, but if you read all the posts you'll see that i found the problem, and fixed it.

And I don't have a cat - cars made before october 1983 don't require them.
