Problems With My Rb20det

[ceffyboy]

hey guys ive just replaced the rb20det in my ceffy with another 1 i got it all hooked up and started it and didnt seem to run right it sounded like the timing was out and wasnt firing properly and also pissing out black smoke so somehow to much fuel. i though it might of been an electrical fault since then i have had it at the auto electrician and he cant find any problems in the ecu or harness. the coil packs and sparkplugs are fine to. its possibly the crank angle sensor but thats all i can think of anyway

would any of u guys have an idea of wat i mean or would be able to help solve my problem?

cheers wes

Clean all the sensors with contact is the first thing id do and also make sure all the wiring to the sensors is done properly. get timing checked (cas should be dead centre), also find out if your acutally running rich or lean as even tho it spits black smoke it might be leaning out everywhere else.

um i had originally the r32 rb20 in it and swapped with another rb20 from an r32 aswell so it should run just the same as the last one shouldnt it?

all being well that is but yea it was just a basic swap

Sounds like one of your injectors are leaking badly.

Try swapping the injectors with your old ones. The solenoids in the injectors can f**k up after sitting for a along time.

hey guys just letting u no i changed the injectors and a new fuel rail and diffirent coil packs now its doesnt seem to have spark maybe i havent put a plug back in properly but yea i cant see a plug that hasnt been plugged in.

so im getting fuel ok now but no spark would any1 have any ideas?
