E30 won't start

hay guys pretty new to this site ,but with a dodgy e30 i think i mite get to know everyone quite fast.

Have just fixed a coolant hose as it had a hole and was causing the car to overheat. now when i tried to start her up and test out my new hose it turned over but wont start. would like to know everyone's thoughts maby common problems. i suspect fuel/ fuel pump or maby the starter coil? i haven't really tested anything yet as its pooring down and i dont have a garage =[. i have tested the fuel pump relay and it seems ok.

my car has this issue currently but they have tested and ruled out

Fuel pulp
fuel pressure
injectors
the ECU
Crank position sensor
the fuel relay ( its located on the driver side wheel well )

it gets spark but they suspect its too weak so they are replacing the ignition system its the original system so if thats the case id check your distributor cap and post a pic of it cause im thinking thats what it is with my car.

I recommend you check all of those

Did any electronics/electrics get wet in the coolant system fix. Check those things.

i dont think that they did. i checked for spark last night and thats algood. but i took out the main relay and noticed alot of rust inside so ill get a new one today, could the problem be as simple as a faulty relay ?

okay so last nite i think i got alot closer to finding out the problem, i managed to start it after cranking it for about 10sec and holding my foot flat on the accerlator pedal untill eventy it coughed a bit and stared up , it ran fine didnt over heat and wen i turned it off thn back on again it started fine. does this mean i have a dodgy fuel pump ? or blocked filter? or both lol

wld change the filter first..if it cranked after you held the pedal down a while then ur problem is somewhere in the fuel system i would think..check the spark plugs as well

Bosch or NGK plain copper plugs. Stay away from the four-prong versions.

I 2'nd 3'rd &... this
Bunch of advertising hype Bull**** (I hope my wife, who worked in the advertising industry for 12+ years, does not read this ).
2- prong or V-groove make sense to an extent.
I don't know why, but the Super-4 sometimes makes cars run worse, such as the Toyota F-series engines found in the old Land Cruisers

But getting back to your problem.
It only starts, after cranking for some, while when it has stood for a period ?
Then it usually is the fuel pressure dropping to such an extent in the fuel line, that it first has to fill again.
Culprit is either the Fuel pressure regulator leaking or (more likely) the one-way valve in your fuel pump.
The chassis pumps seem to be Ok on this, but the one in the tank often goes fauly ????

always go ngk plugs..and he said he has to hold the pedal down a while 2 so maybe somethings blocking the gas from getting where its suppose to be in the filter..but let us know when you switch them out

If possible check fuel pressure in the rail.

take fuel line feed off and see if petrol comes out when you turn the key to ON but before starting. not sure what non-BMWs are like, but these cars prime for a second or two before starting. that will help determine if the fuel pump is working, though it could still be non working up to spec. there is a filter on the tip of the pump that can get blocked too IIRC, i can picture the E34 pump but been a while since i looked at an E30 one.

Anyone know where the non-return valve is located, in the in-tank pump on the 323 ?
mine sometimes holds pressures & other times....
