1990 1.6 CVH with EFI

Does anyone know the correct (standard) pressure that the fuel pump should produce and also the correct (standard) pressure that should be in the fuel rail?

Cheers

 

Not too sure myself on the pressure, but the fpr should sort it to the correct amount in the fuel rail.
Sorry can't help mate, someone will know

 

Wanted to know what pressure the fuel rail should be as we think the FPR could be off as we found a SHONKY NUT on the adjuster

 

I've got a couple of pictures of zetec 2.0 and rs fpr if that's any good?? Doubt it but maybe you could make out from the numbers what it should be??

 

You never know it may do

Thanks for the email mate but they are the sealed ones. The one we have is the earlier adjustable one arrowed.



We think this has been messed with so want to get it back to standard to prove if it's faulty or not

 

Yeah they used to wind them up back in the day. cant you do a few test runs to see how it runs while turning it down?

 

Unfortunately not you see the EFI is SHONKED with Induction kits, bad exhausts, setting all over the shop, causing rough running, flat spots etc.

So we are gradually going back through the whole system gradually ticking the boxes getting it back, but this is the next thing. We have managed find the pressures should be 5.0 bar fuel pump and 2.5 bar at the fuel rail but wanted to get this confirmed.

Done so far

Standard Exhaust fitted
Standard Air Box fitted
Trottle body cleaned out
Idle valve cleaned out
pipes checked for leaks
Breather cleaned out
New plugs
Fuel pressure from pump = 4.0 bar
Fuel regulator... Next...

 

Your pretty much on top of it now then, might be worth a full self service if you havent already. obviously your half way there lol. FPR sorted, fuel filter, etc. Should come up sweet

Whats the milage like?
