L200S Need help again...

[mouse8899]

I need help from you sifus again....

Ok, since alternator problem was solved this was another one that has been bugging me till I burst my head.

Firstly, when the car was brought in, fuel pressure at the fuel regulator was reading 6 (if not mistaken)
No weird noises on the fuel pump. Then a few weeks later, there was some weird noises on the FP like it's suffocating (something like sucking a hollow end plastic bag with your mouth) and pressure reads 4.
pressure goes up a little when revved, probably near 5. Sometimes on idling will hear it rev a little then stall a while. Stall in just 1 second interval. (Like *vroom* stall *vroom* stall)

Secondly, when I engage the clutch after shifting gears (I mean all the gears 1-5&R) any of these, the car straight away silent mode(even quieter than idling) and no response on the engine even on full throttle. I have to maintain some throttle and the clutch at certain levels to keep it moving (as in slipping the clutch) to move the car. But this didn't last long, probably in 2-3 mins the engine stalls on me.(Felt it was stalling, clutched the engine & let go of throttle) On idling, no problem. But when the gears are engaged, this happens.

First time encountered this kind of problem... no idea how to solve it

Things that I could think off:

1. Clog somewhere? first by replacing the fuel filter... if not then work your way the fuel lines to check whether its clogging
2. electricity, your previous post mentioned that you have issue with wiring... could be it affecting the fuel pump. do check its wirings and relay
3. replace the fuel pump altogether... a hint, wira 1.6 fuel pump bolt right up and could be used up to 200hp if you feeling naughty with the engine

my guts telling its some gearbox issue... I'm going to my fave pomen this evening, I'll ask him and post his answer here later

Haiyo! no expert la... just happen to friend some otais and sifus la....

firstly, throttle body?
secondly, too much engine oil?

   ok will check on the fuel lines
2. electricity, your previous post mentioned that you have issue with wiring... could be it affecting the fuel pump. do check its wirings and relay
   borrowed a new set of wiring from the chop-shop today, fixing it up in process... old wiring many fly here and there on the relay side, even you see also :hmmmm:
3. replace the fuel pump altogether... a hint, wira 1.6 fuel pump bolt right up and could be used up to 200hp if you feeling naughty with the engine
   that would be the last resort

my guts telling its some gearbox issue... I'm going to my fave pomen this evening, I'll ask him and post his answer here later
ok, thanks... when ever under load it happens. but if jack the buggy up on jack stand, running smooth gao gao
the other day when replacing valve cover rubber seal found the valve train sludge everywhere, mostly hardened sludge on the tappet side, could that lead to this issue?

firstly, throttle body?
secondly, too much engine oil?

throttle body inside is clean, don't think it cause this issue. but there is 2 hose fittings under the throttle body that is left open. no idea where it goes to. buggy not using brake/clutch booster, just individual cylinder
engine oil level is ok

shown my pomen this thread yesterday... he also no clue

he says need to see it for himself...

as per sludge issue, try clean it up and test again.....

tried to clean up without taking everything apart... unless have to do full overhaul, just scared after overhaul and still the same result and waste a lot of time. for the time being swap in the wiring and try first
if you got any word on this problem, please give some tips here

Probably your clutch housing is worn out...

Also check your fuel filter if its clogged with dirt...

Only 2 possible fault i can think of...

it's a new clutch set.. that's why i still pening pening

I also pening la if like that means......

**check for any loose hoses. especially the throttle body hose, check that 1st, then move down to the rest.
Secondly, when I engage the clutch after shifting gears (I mean all the gears 1-5&R) any of these, the car straight away silent mode(even quieter than idling) and no response on the engine even on full throttle.

But when the gears are engaged, this happens.
**try to shorten your clutch pedal. there is a screw just above your clutch pedal.

 

[mouse8899]

will try every possible item listed

 

[DanzEterna]

hows the outcome?

 

[^pomen_GTR^]

most probably would be fuelling problem.....try injector cleaner after checking fuel pressure and all the fuel related piping

 

[mouse8899]

i havent got any updates yet from my colleagues, i was on leave for a week. next tuesday i'll be back and see how it goes

UPDATES ON THE L200S BUGGY

Boss had a wireman came and rewired the body wires, previously was only 3 relays with 6 outputs. Now each has individual relays and fuses. Body wires have been replaced with higher ampere ratings to prevent any resistance in the current flow. Previously the fuel was not completely burned and smell very strong on the exhaust, now after rewired no trace of unburned fuel + got minor vapor come out. No choice... have to get the wireman, we all too busy concentrating on the main project

Then concerning the noise on the fuel pump, the previous alternator "kong" already. That's the main reason so noisy. After replaced with recon one no noise already.... for now la

Issue on the engine no power after gear engages, all the problems solved except this one. We were told by boss that the headgasket was blown before because overheating, it was not repaired properly after that by other shop. They just simply change the block. I mentioned before about the sludge, that guy go rallying turbo not using filter... I suspect the sludge is very thick at the valve area causing compression loss. I SUSPECT ONLY AR.... boss haven't give any orders yet on how to solve it, so leave it be for the time being.

Now focusing on main project, almost finished the chassis, by next week can prep and spray already. Hopefully can finish before March...

 

[papagoines]

can show pic? interesting project you got there

 

[mouse8899]

finish prepping already today, tomorrow 2nd layer primer
