I'm trying to fix a 91 m30 convertible that has been sitting in a garage for 10ish years. Rust is minimal from being kept indoors, odometer reads 83k miles. I replaced the fuel pump and filter, oil and filter, and spark plugs. I ended up breaking the distributor cap but got a new one, wires and coil all worked fine. I know I have spark (used an inline spark tester) and used the self diagnosis mode on the ECU which resulted in code 55(no faults detected I think). Will crank but wont catch, using a little starter fluid will make it catch for a second which makes me think the issue is still fuel. If the ECU is saying nothing is wrong, is it something with the injectors or maybe the ECU itself. I could really use the help, I don't have too much experience with older cars like these.
