right to cut a long story short refitted engine into my typre r v4 my98 car turns over fine but will not fire up, if i spray engine start down the air intake it fires up ( short term due to using up spray) but wont fire without doing this, so am assuming that its a fuel problem as also ahve a good spark so far i have checked fuel pump ( all ok) checked fuel lines are the correct way around, looked for leaks etc but all to no avail, i replaced my injectors (yellow 440s) when engine was replaced old ones were no good, but they also seemd fine anyone else have any ideas as am running short of them and this needs sorted thanks in advance.

 

any codes show up when the black connectors connected?

 

Make sure your crank sensor is plugged in

 

Blocked injectors !

 

Crank sensor plugged in mate, should I take out injectors and unblock them?? Only fault code I can see ( think its old also) maf sensor but that wouldn't stop car from firing just have adverse effect while running I assume.

 

Remove plugs & crank over on starter if it's injecting fuel you'll see it misting out the plug holes. Unplug coil pack first though.

 

Check for injector pulsing. Its highly unlikely all 4 injectors are going to be blocked. Are the plugs on the correct injectors. Very easy to put on wrong. Do you have fuel in the fuel rails?

 

Flow and return fitted the wrong way?

 

Flow and return fitted correctly guys, ill check to see if the injectors are fitted the correct way didn't realise that they could be fitted the wrong way around cheers

 

Not the injectors themselves. The plugs can be put on the wrong injector. Cant remember which way they go. I think its black plugs at the front and grey at rear. But i could be wrong in that

 

are the crank and cam sensors original or what came with the lump ?

 

This is true but I also recall you can accidentally mix up the cam sensor plug with an injector plug. Also make sure the coil is not on upside down & the correct lead is on the correct cylinder.
