That pressure reading has nothing to do with gas pressure supplied to the Sniper . Your bet bet is to install an electronic fuel pressure gas inside where you can see the pump pressure to the Sniper, it's got to be approx 59 psi . The gauge from glowshift works great .

Charge the battery, get someone to help you. Look down the Sniper while you have them turn the switch on only ,you should hear the pump start up & stop when its pressurized ,you should also see the Sniper deliver the fuel prime squirt into the eng .

When you turn the key on the handheld should light up with all the info, if it goes off at any time during trying to.crank it that's a bad problem as the system will be rebooting . It's got to.have a constant 12 v supply ign on & starting . Got to have a 12 volt or better charge on the battery .

I read a lot about the filter in the pressure regulator getting full of crap. Your tank & pump look to be a good install .

A lot of the Sniper issues are diretley tied to improper wireing or o2 sensor problems caused by exhaust system leaks .The 2300 on the 200 in my 67 has been fine for the most part other than o2 problems from exhaust leaks .

Look on the Holley Sniper forum .lots of info on there with some pretty smart people . You have to just look over all the I hate that piece of crap Sniper people .

I've had mine on close to 3 years & no way I would take it off to put a carb back on .

From every thing I've been reading you can't have to many good clean grounds. Eng to firewall,to frame firewall to fender aporns .My self I've just purchased & installed 2 new painless ground straps kits on my 67 200 . In the end I don't think I really needed them but I was haveing a problem with getting it to fire after installing a Hyper Spark dist for Sniper controlled timing . Turned out I did'nt have the 10 pin part of the Sniper harness i needed .

A word of warning if for some reason you try to disconnect the handheld connector from the Sniper main harness, read your paperwork and watch some detailed videos of how to do that . Trust me you can pull the Sniper part of the connector off the harness & it's a bitch to try & figure out a repair for it other than send it to Holley for a new harness or ecu.

But it can be made to work again .
