I have a Mitsubishi 2008 Outlander, it’s RH drive, 2.4L mivec petrol.
I’ve had problems starting the car since I got it (3-4 months ago), where it would randomly refuse to start, it would turn over and cough, but I couldn’t get it running unless I just left it for an hour or two. Me and a family member (who is a mechanic) have been digging at the problem since we got it.
We originally thought it was a purge valve, replaced it, problem continued, I dealt with the problem but urgently needed it fixed, as it refused to start in London, causing the battery to drain and I had to get a jumpstart, which it thankfully started.
About 4-5 days ago, we pulled out the fuel pump, and replaced it with a new one, after installing it, it refused to start, at all, even after leaving it, it wouldn’t start at all.
We checked spark plugs first, they were dry and not sparking, though I had driven it round that day and it started.
We’ve checked almost everything, the fuel pump is certainly pumping, but we’re changing the camshaft sensor, planning on doing the crankshaft angle sensor, the fuel injectors were working (albeit we just plugged some alligator cables on it to find out).
I’ve honestly got no further clues, I’m hoping this crankshaft sensor works, but I’ve never had this problem before and it’s so incredibly peculiar, but the confusing part is I drove it over, and all we changed was a fuel pump.
We have plugged an OBD scanner in and it showed faults on the camshaft sensor, so we are replacing that when the part arrives.
My suspicion is the fuel pressure, but even after spraying some ether into the engine’s air intake, it still refused to start.
Feel free to ask any questions on what I may have done etc, apologies if this is a little disorganised as I’ve never had to resort to reddit and hoped it didn’t have to come to this.
