Before I took the Caddy off the road, it had been suffering from increasingly erratic reliability. It had begun mis-firing and cutting-out, and had me convinced it was a fuel issue. As I mentioned in my previous post, I had installed a fuel cut-out circuit, but for reasons of expediency I had connected this to the high current side of the fuel pump relay. This was a mistake, and the relay I had used to implement the cut-out had not been up to the job, so it had failed a while back. This relay had been replaced, and it appeared to have sorted the issue, but the same symptoms had re-emerged afterwards. I re-configured the cut-out circuit to switch the low current (coil) side, and hoped this might solve the problem. When I drove the Caddy off to JKM for its MOT, a journey of about 20 miles, I got about halfway before it started playing-up. On a couple of occasions I thought it was stopping on me, and my son, who was following me, said it produced some sizeable blue flames through the exhaust, but it kept going to get to Portsmouth. The MOT test was passed, which was obviously welcome news, but I left the Caddy with JKM waiting for them to have an available slot to test run it on the dyno. While I was waiting, I decided it made sense to replace the fuel pump with an uprated one, whether or not it was found to be the cause of the problem. The pump that was fitted had been swapped-over from the Felicia when the 1.8T transplant was done, and for all I know was a standard Felicia 1.3 or 1.6 part. Jim at JKM decided, probably wisely, to try to replicate the fault on the dyno before the pump was replaced. Sure enough when it was run up the fuel pressure was all over the place. A Deatschwerks 265lph in-tank pump was duly fitted into the Caddy. The spark plugs were also replaced as they were overdue. The subsequent dyno run showed the Caddy now making 200bhp (well 199.6, strictly speaking), up from the previous 180bhp. Happy days. One frustrating aspect related to the increased power is the fuel that the Caddy was running on at the time. I seek out Shell V-Power whenever I can for all of my cars. If I cannot get V-Power then I will go for BP Ultimate 97 octane. The Caddy had not been anywhere for months before I drove it to Portsmouth for its MOT, and the fuel gauge has not always been 100% dependable, so when it first started playing-up going to JKM I thought there was a chance it may be running low on fuel. I did not dare risk striking-out for the BP station five miles or so further down the road, so I stopped at the closest service station, and put £30 of normal unleaded in. The first time the Caddy has ever had anything but super unleaded in it, and that was when it goes on the dyno! There was a slight mis-fire showing-up at high revs on the dyno, so new coil packs were recommended. Luckily enough, I had some replacements in the shed, so no additional expense was incurred in putting that right. The difference between 180bhp and 200bhp really does not seem like it should be noticeable on the road, but the Caddy feels distinctly quicker than it did previously. I still need to get the suspension geometry done, as it is currently as I set it 'by eye' during the suspension rebuild, but I have been busily reacquainting myself with how much fun it is on the road.
