    trouble shot ready to sell my car

    Ok so I took on a e30 24v swap that I bought from a friend in pices the car is back together and idels really strong. My problem that's all it does is idel. When the motor is put under a load it bogs down and ideals like crap this is the trippy part you can turn the key off and start the car back up immediately and it runs just fine until put under load again. The car has not thrown a single code as far as I know because the cel has not came on which doesn't always mean there isn't a code.

    Things I've done new injectors, new maf, new vaccum hoses, new 190cfm evo fuel pump (chip is tuned for).

    Any and all suggestions are welcome I'm pulling my hair out

    Did it run good ever? Head been off? Timing chain been off?

      The original m50 that was in it before I got it ran like a top until they hydrolocked the motor. So I bought it from my friend who had purchased a running m50 with 70xxx miles to go in and that motor came from a running car that had been hit in the rear and totaled out. So it was pull the old and in with the new and considering the swap had been done already it seemed easy plug and play. Basically I got a bimmer in a box assembly required..... I wanna say its a fuel issue I bought the fuel pump used from a guy who had it in his car for a month and changed it out to a bigger flowing pump because he wasn't getting enough fuel.... Hmmm Epiphany... Also have to check fuel pressure regulator... Vaccine line off bottom of intake goes to the fuel pressure regulator?

            If it idles and revs up fine in the neutral but dies in the gear maybe you have an issue with the trans, clutch, flywheel setup. Doesn't sound like a fuel issue

                To add it will run long enough to get to about 25 before starting to putter out and ideal rough. But can turn the car off and right back on and it runs fine until about 15-25 mph

                  OK...are you 100% certain you have the fuel lines correct?

                  You might wanna pop them off, make sure the one with the pressure goes to the fuel rail input.

                  Test the flow while you are at it, as a ghetto test, squeeze the line with pliers as it is dumping into a 1 gallon fuel can. If it shuts off with not much effort, that pump might be crap.

                    I went over all my fuel lines again turns out that the fuel line that connects the fuel pump to the sending unit was not tight enough so it would build enough pressure to idel but once put under load I lost all fuel pressure. But went and bought new fuel line an the proper fuel line hose clamps for a easy fix to a head scrater of a problem.
