G'day
i finally finish replacing seals (cam, crank & rear main), put everything together, started her up and she was alive again. not for long. i installed new fuel tank guard from Fatzook and drove to shop. when i wanted to start her in the evening, she started, straggled for few seconds and died. I thought it was carby playing up, try to push start to no avail.
next day i add 5l petrol from jerry can, just in case (fuel gauge shows null for full and empty tank) and tried to start her, no luck. start de bastard didn't help, so i poured some juice to the carby, she started, run for several second and died.
I checked:
-fuel filter - not blocked
-disconnected main cable from coil, undid the fuel hose at the carby end and let my brother crank it to see if fuel pump pumps, few squirts and nothing.
-disconnected inlet hose to pump, petrol was there, so can't be blocked, hose between fuel pump and carby not blocked.
-I didn't check fuel pump return hose - should I?? i guess no need for that
so my diagnose is fuel pump is dead.
1. DO you confirm that or something else could be wrong like blocked pump (if that's possible)?
2. here's the picture of fuel pump. i have G16a in my sierra, but no idea if that's 1.3 or 1.6 head and if fuel pumps are different for 1.3 and G16a engine?
can anyone confirm which fuel pump is it - from G16a or G13a i don't want to buy wrong one
3. here are pictures of my carby. choke plate is open when engine is cold and the spring (indicated by red arrow) which close it is very week,
choke doesn't work since a while. she used to cold start no problems, just no choke, but had problems with hot start. was running too rich and consumption was too big. is it because that spring being too week and that choke plate being open all the time?
4.where i can get this spring from (new one ideally)??
5. she idles ok, but i need to regulate idle speed once for a while. sometimes when hot and worked harder idle was higher. before problems with fuel pump i sprayed start u bastard on each vacum hose i could find and revs didn't change so i assumed there is no vacuum leak
i cannot find manual for vitara carby hence i can't find mixture screw. the one i indicated by red arrow doesn't do anything. i guess is supposed to regulate the movement of the rod going to actuator (don't know if that's idle or secondary one), but it doesn't matter if i screw it in or unscrew, it changes nothing. anyone can help me with this?
few more shots of the carby.
so if u do it before me let me know how you go
Efi rock's..
