vfb Posted January 4, 2021 Author Share Posted January 4, 2021 Yes, hit and miss but mostly hit today. Starts and restarts pretty well. I think I'll go at cleaning all connections. Maybe the distributor cap is dirty inside like you say :) Link to comment Share on other sites More sharing options...
MiNi Beast Posted January 4, 2021 Share Posted January 4, 2021 moustiure build up when plowing is very feasible. even going through a mud hole i get same symptoms. my cps is due to be changed as well. i have a brand new in parts box. might as well get it changed i reckon, said to be 38* today. good day to work outside.

It started at .4 then fluctuated between .6 and .8 Is this ok or too much? I know .5 is ideal. These are good readings. Time to move on to the next items. However, if it starts cranking but not starting again, this would be the very first thing I would check. The four things you need for a running engine (in order of likely fails) are: Spark Fuel Air Compression/ Timing You can check for spark at the end of a plug wire like MiniBeast says. If that checks good and you are still have a no run condition I would move on to fuel. Any auto parts store should rent you a pressure gauge for "free" ie: you put down a deposit when you check the tool out and get that money back when you return it. Should be 31 psi with the vacuum attached at the Fuel Pressure Regulator and 39 if you remove the vacuum hose. Good luck! Link to comment Share on other sites More sharing options...

vfb Posted January 5, 2021 Author Share Posted January 5, 2021 Could the CPS test show different results in a no-start situation compared to when it starts fine? When I tested, it was in a good phase where it seemed to start .......that's when i tested. Then it ran well for about 10 or 15 minutes while I drove around and pushed some snow for a bit, but then it quit and wouldn't start for an hour or two. This seems to be a pretty consistent pattern. I'll have to jump on testing for spark as soon as it quits obviously. Link to comment Share on other sites More sharing options...
MiNi Beast Posted January 5, 2021 Share Posted January 5, 2021 swap that cps. Link to comment Share on other sites More sharing options...
MiNi Beast Posted January 5, 2021 Share Posted January 5, 2021 also that cps could be getting wet from the snow pushing. could also be getting heat soaked from pushing the snow. seems you have spark fine so still leaning towards cps or plug connection on the cps. have you inspected under you distributor cap yet?

vfb Posted January 5, 2021 Author Share Posted January 5, 2021 I ran it for about 10 min again today and it quit again. I brought the multimeter with me and I tested the CPS when it wouldn't start and got a zero reading. Could this be right? Going from a great reading to 0? I'm pretty sure that I had good connections. It seems heat related and I also tried another coil I had around, but no luck. Haven't yet been able to test for spark in the no-start scenario but tomorrow will have a friend here so that should help. And....MiNi....... I will look at the distributor but it stalled inconveniently and too far away. Once I get it started (hopefully) and get it closer I'll try that too.

MiNi Beast Posted January 5, 2021 Share Posted January 5, 2021 only need a philips head screwdriver and lift cap and take a look. however still say swap out that cps Link to comment Share on other sites More sharing options...

JustEmptyEveryPocket Posted January 5, 2021 Share Posted January 5, 2021 1 hour ago, vfb said: CPS when it wouldn't start and got a zero reading Sounds like its time to break out the extensions, learn some new curse words, crawl under the truck, and change out your CPS. I recommend getting one from NAPA as they seem to have the best track record. Either that or see if @eaglescout526 can hook you up with an OEM version.

eaglescout526 Posted January 5, 2021 Share Posted January 5, 2021 There’s still some left. I think they are going fast. Link to comment Share on other sites More sharing options...
vfb Posted January 5, 2021 Author Share Posted January 5, 2021 Ok sorry.... correction. When I say "pretty sure I had good connections", I should have said "not sure" . I just did it again and got readings of .6 and it hung in about .8 while still in a no-start mode. I hope this means the CPS is ok. I do actually like the idea of trying it myself sometime but also I'll admit, "the older I get, the colder I get". Doing it for the first time while lying on the frozen ground, (even with new curse words ready), really doesn't appeal. If I can put it off for a few months it would be better. 6 minutes ago, eaglescout526 said: There’s still some left. I think they are going fast. Thanks for that offer but since I am in Canada, and the fact that I use it for plowing and need to sort this out before the next snowfall, I think the timing with shipping isn't good. So, attaching spare coil didn't help CPS tests good too dark to look at distributor today :( Tomorrow, try to get a no-start when I can have help checking spark Link to comment Share on other sites More sharing options...
cruiser54 Posted January 5, 2021 Share Posted January 5, 2021 Make sure the CPS harness is routed correctly, and not laying on or near the exhaust manifold. Wouldn't hurt to do Tip 2. Link to comment Share on other sites More sharing options...
JustEmptyEveryPocket Posted January 6, 2021 Share Posted January 6, 2021 If it was my truck I would look for bright blue spark at the end of a plug wire during a no start condition. Then I would get a fuel pressure reading. That will help you narrow your search. Link to comment Share on other sites More sharing options...
