Pay Core Charge Upfront - Charge is Refundable You may contact us to ask for an exception to this policy. These are just a few 7.3 Power Stroke problems issues to keep in mind on a crank no start.As of November 2021, the standard practice for The Diesel Store is to collect a refundable core charge at the time of purchase. If you have only 3 glow plugs working and you use starting fluid on it you are going to cause engine damage very quickly. AAAhhh do not use starting fluid on a hard start.
That's because they are located under the valve covers. It is only a matter of time till all the glow plugs fail. When your truck losses one glow plug it will become harder and harder to start. Yes that is alot of amps so be sure your battery and charging system is up to par. Now the glow plugs will need to pull about 180-190 amps when cold. Even if it makes a click noise, verify the relay has really switched power. The Two other terminals smaller in size, One is key on power from the ignition switch and the other is a ground controlled by the Powertain Control Module. One wire will have B+ all the time, across from it on the other big post this is the feed to the glow plugs. do not go poking around on these wires it requires a different set of tests.) Most PSD's have the 4 post relay. Also on some models the glow plug relay will look like a mini control module. (note sometimes there are two relays next to eachother one is for glow plugs and one is for the intake heater. On most PSD on the passenger side on the engine on top there will be a relay. Generation one and two powerstrokes will vary in their glow plug control, but I will keep this simple. If it is not cranking fast enough it won't generate a signal for the camshaft position sensor. If you have a tach guage does it move? If the computer does not see a tach signal it will not turn on the fuel. A common 7.3 PSD problem is the fuel bowl heater shorting out under the fuel filter, which in turn blows the fuse. This fuse will operate the fuel bowl heater and a power circut for the powertain control module. Turn the key on, does the "Wait to start light" come on? If the light does not light up check the 30 amp fuse under the steering wheel. One to lubricate the engine components and the other to operate the fuel injectors. Unlike other diesel engines the Powerstroke has two oil pumps. Your engine could be low by just 3-4 quarts causing a hard start. The first step in a 7.3 no start is to simply check the oil level. So lets put down that can of starting fluid and figure out why it won't start instead of causing more damage. Help my 7.3 Power Stroke cranks but will not start.
