Question about 2007 Mazda B4000

Mazda B4000 intermittant cranks but won't start - no spark

I have a 1997 Mazda B4000 (same as a Ranger 4 liter) PU 2WD, only 80k miles, had the CPS replaced 20k ago. For no reason at all, on occasion with no predictability or reason, from cold only, the motor will crank and crank and crank but will not start for hours. I come back and bang it starts. It has never done this hot, never two days in a row and it only has been doing this about 6 months after replacing the CPS.

We checked for spark when it did this and no spark, but a smell of gas. So I replaced the distrib coil. I was going to replace the Ignition Module, but the Mazda/Ford dealer parts guys laughed and said they virtually have no history of these failing, none even in stock, even from the warehouse!

What the heck is the problem with this truck????

    It was the CPS - camshaft position sensor. Oddly enough, the original one had been bad (physically broken) for over a year, but the engine ran / started perfectly and never had this issue (intermittent cranks but won't start when cold - no spark). But the DMV won't allow Smog Cert if there is a Check Engine Light even though the engine passes smog! So I had to have it replaced to Smog Cert it! The Mechanic said in the late model 4.0L V6 Ford motors, the CPS does nothing and isn't really needed! Is that not true? So if the original was physically broken, and the engine did not have this issue, why is it now with a replacement CPS??

CPS? You replace the crankshaft position sensor on the front of the engine or the camshaft position sensor on the rear of the intake? Was it doing the same thing before you replaced it. You might have got a bad one.

    It sounds like a bad crank sensor. Also you say the check engine light is on? What code is in the computer?

The generation of the Mazda B-Series produced from 1994-2000 also shared its platform with the Ford Ranger. Initially these B-Series trucks came in base, midgrade SE and luxury-level LE trims in standard- or extended-cab body styles. There was a choice of three engines: a 2.3-liter inline-4 (98 hp), a 3.0-liter V6 (140 hp) and a 4.0-liter V6 (160 hp). Transmissions consisted of either a five-speed manual or a four-speed automatic. The V6 versions offered a choice of 2WD or 4WD.
Model-year 1995 saw the debut of a driver-side front airbag and ABS as standard equipment for all B4000s and 2WD B3000s, while '96 saw the addition of a passenger-side front airbag in the upper trims. A five-speed automatic debuted for the B4000 in '97. A revamp took place for 1998 that included freshened styling, a stronger 2.5-liter four and a revised front suspension for better ride and handling dynamics. For 1999, the Cab Plus 4 debuted (essentially an extended cab with a pair of reverse-opening rear doors) as did the flashy Troy Lee edition.
At the time, we noted in Mazda B-Series reviews that the truck offered a good selection of configurations and attractive styling. Downsides included the limited functionality of the truck's rear seats and the lack of horsepower from even the top V6 engine.
Previous to 1994, the B-Series was all Mazda. The B2200 with its 2.2-liter inline-4 and the B2600i with its 2.6-liter V6 were offered in standard and extended cabs. A five-speed manual transmission was standard with a four-speed automatic optional, while only the B2600i could be had with four-wheel drive. Although these were decent trucks, the chance of finding one of these workhorses in good condition is slim, as they're well into their retirement years.

1994 Mazda PU Truck sometimes won't start if shutoff for 5-10 minutes.. Several tries later, it will start. spark seems ok, it gets enough fuel for a second, but then poops out. fuel pump shuto


Well there is no shutoff relay, but there is a fuel pump relay that powers the pump.
I would check it first. The computer grounds the relay for 3 seconds when you crank the engine to boost fuel pressure. Once the engine starts the pump is powered only if you have oil pressure.

1998 Mazda B4000 (similar to Ford Ranger). Wipers, dome light and 4 wheel drive selector switch work intermitantly. I would like to know what is the problem and what parts should be replaced. Mike


With it being an intermittant problem that indicates a possible electrical short. It's not likely that any parts would need to be changed. I hope this is helpful.

Ok, you need to keep checking other related items. How is the charging system, tune-up history, vacuum lines, braking (vacuum booster), and the fuel system (how is the fuel line pressure and has there been any issues with water in the fuel)?

Wont start .but when it does it runs fine


you should be able to hear your fuel pump run like a zingggg or a errrrrrrrr noise get someone to cycle the key to the run then off position while you get close to the fuel tank if you hear either of those sounds the pump is running. if you wanted to go a step further i do believer there is a valve on the fuel rail that looks like a tire valve and if you can get a presure guage on it it should read 45 -50 psi i do believer but as long as you are getting some pressure your truck should idle. check the fuel filter too .
