Hi, My e36 316iA with m43b16 engine left me stranded on the state highway 1 last Sunday, I was doing 90kph slight downhill when the engine just lost power and rpm drop to 0. I taxied the car to the side of the road and checked the oil and coolant as I thought the engine seized, but both coolant and oil look good. Next, I pulled the spark plug, and I can see spark going and the spark plugs seem normal with good a bit red-ish color. I tried to start the car, it just cranks and won't catch at all. I jumped the fuel relay and I can get 12V and ground to the fuel pump, but the car still won't start. At that point, I thought I have a bad fuel pump, but when I took the pump off and bench tested it with a spare battery, it pumps fine, enough pressure to shoot gas right onto my face. So I changed the inline fuel filter, and it doesn't help either. I also checked the fuel pump relay coil side pin 85, 86, 30, 87 I am getting 12V at the fuel pump, so 87- fuse - pump circuit is good, and I bench tested the relay, it is working good. Pin30 is getting 12V at all time which is good, I am getting 12V from pin 86 when DME is turned on, but I got a strange 0.02V at PIn 85 and no continuity to chassis ground. I read it somewhere that a bad crank position sensor will stop the coil side of fuel pump relay getting power, so I tested it, and it seems good apart from quite dirty. In addition to that, I cleaned the MAF as well. Now I have put everything back and it sometimes starts but won't idle, and sometimes won't start at all. I pulled the plugs again, and there is black soot on the plugs? I was under the impression that I am not getting fuel so no start, but why is there soots on the spark plugs from I trying to start the car? note that when the car first broke down, the spark plugs look good. I am out of ideas, please help. as the problem is kind of interment. to conclude the problem above. When first broken down, won't start at all. Then after I took the fuel pump off and put back on, together with a new fuel filter, it won't start but catches sometimes. After I tested and cleaned the CPS and MAF it starts but won't idle but will stay at 1500rpm if I give it some gas. However it eventually died even with throttle input, and I discovered spark plugs covered in black soots. I cleaned the spark plugs, and now it won't start and catch occasionally. I think I should do a fuel pressure test, but I don't have the gauges and being a poor uni student, I am not going to tow it to the shop and pay for the repairs. Does anyone in the forum have fuel pressure gauges is kind enough to lend it to me for a few days? Sorry about the long and unorganized text written in shitty English, thanks in advance for advices and suggestions.
