E30 Zone

i have a 1987 325 i m20. recently i took the inlet manifold off to spray it i also replaced the fuel hose and replaced some of the gaskets. i tried to start it on sat and at first it started and ran for about 30 seconds then it popped and stopped. i tried starting it again but with no look all that happens is you can hearit turning over as if there isnt a spark.

i have had a friend look at it and its firing and has a good healthy spark on all the plugs its pulsing properly like it should be and it has good fuel pressure. so i then took it to a local garage for them to put it on diagnostics but they didnt hav the software.

i was just wondering if anybody could shed some light on the problem?

i am desperate to get it running again.

please help

Fuel pipes back on the right way round?

yeh put them on the same way they come off.
