Long cranking times.

[Ryan]

Ahhhh makes sense. My old gauge was a homemade piece. Remember now, that I waited a bit before disconnecting the gauge to let the fuel press bleed off.
GNRick, thanks for the idea. They have one at the parts store. Can't imagine that I will use it that much so FREE is always good.

Does the car misfire on start up? Somehow your losing fuel supply in the rail. If an injector was leaking down you would most likely have a misfire on start from the fuel in the cylinder. Make sure the tester you use has the clear hose on it. The main reason for the hose is to check the volume of fuel . A stock pump with fill a 20 oz bottle in about 20 seconds. Aftermarket pumps will fill it a lot faster. Like stated above remove the inline pump and install a good intake pump and hotwire kit. Most likely the check valve in your pump is bad and that is what is causing the extended crank. I had a sx inline pump and when my intake pump check valve went bad it did the same thing.So what Im getting at is the inline pump might not have a check valve in it. I dont think my sx inline had one because when I replaced my intake pump the problem was gone. When you have the gauge on there the pressure should go right to 45psi or what ever you have it set at right away as soon as you turn the key. If it climbs slow its the pump. If you key the car up with out starting a couple times it it will probably start right up. that's the pump having to fill the fuel lines and build pressure. I hope this helps. good luck

Where can I find a cheap fuel pressure gauge? Not looking for a permanent mount.....just a hand held model. I have seen many for sale online.....is the connector universal? If not , what size do I need?

A "cheap" fuel pressure gauge/tester might not be the way to go. I got one from Sears. It was reading low by 10lbs right out of the box. I've also got one of those little gauges that attaches to the fuel rail. That one isn't right,either.

Got a 2 5/8 Autometer Sport Comp gauge in the radio hole. That is right on the $$. It agrees with the replacement FP tester from Sears,and a friend of mine's Blue Point tester.

You've got to have two gauges/testers,or at least make sure yours is calibrated correctly. Otherwise you might be trying to diagnose with a faulty tester. ...and fuel pressure is not something to take lightly with these cars.

hello people; I've noticed all TB don't start write up like I would want. They all seem to take a few revolutions of the engine to start. Someone had a fix but I saw it a while ago and forget where I saw it.

..and if you think you might have a wiring issue such as a bad relay or bad connection,you can do what I did and make the wiring really simple. I've got a 10ga Hotwire ( I think from Turbo Tweak) that goes from the back of the alternator....to a fuse/holder on the back of the alt....to a 30A breaker (which acts as a switch) in the ashtray....then the wire continues directly down thru the top of the sending unit to the pump.

No relays.

To start the engine: Switch on the breaker....watch fuel pressure quickly rise....turn the key...note oil pressure...

Just don't tell Earl about this,he wasn't in total agreement with this idea. But for the last few months,it has worked like a charm. Starts quicker,too.

hello people; Search for (quicker starting for a 1986 turbo Buick) and see what you find. I saw something but I don't think it was the one I saw in the past. I just googled it.

Wow, I had to read that 4 times to figure out what you were trying to communicate.

Faster cranking or starting? Faster cranking you can switch out the starter to an LT1 starter. It is smaller and lighter than the stock one and about $130.00 I got a starter from a 1993 corvette when mine took a digger. Faster starting. Hmm... prime the fuel pump by turning the key ON but do not start for 3 seconds or so. I have "heard" that switching to a LT1/LS1 MAF and translater speeds up start time. Don't quote me on that and do your due diligence.

Yes, a stock ignition set up can take up to two full revolutions before the ECM starts to fire the injectors. This is due to the ICM requiring the cam sync before it can spark the plugs and send reference pulses to the ECM.

Search for the "quick start" and/or "fast start" systems. These were used on later Buicks and consists of two shutter wheels on the crank hub. The engine will even start with the cam sensor unplugged. The system syncs up within 1/3 of an engine revolution.
